In this post we will learn division of large whole numbers.
First we will understand the concept of division.
Then move on to calculate division of any number using Long Division Method.
After the concept we will solve worksheets related to this concept
Concept of Division
In Division we basically separate the number into small parts.
The symbol for division is ÷
If we write 16 ÷ 4, it means that we are dividing number 16 with 4.
Let us understand division with the help of examples.
Example
Divide the 20 balls into 4 parts
The question can be expressed as: 20 ÷ 4
There are 20 balls in the below box.
Now you have to find 20 ÷ 4
It means for given 20 balls, you have to form group of 4
When we form group of 4, we get total of 5 boxes (see the image below)
This means that 20 ÷ 4 = 5
Hence for number 20, if we try to form groups of 4, we will get total of 5 groups
Concept of Remainder
Remainder is the numbers left when the given division is not fully possible
Example
Divide 17 by 4
It means that from given number 17, we have to form group of 4
You can see from above that the number 17 is not completely divisible by 4.
When number 17 is formed into group of 4, we get 4 box of the group and 1 is left as a remainder.
So the above result can be expressed as:
17 ÷ 4 = 4 groups & 1 remainder
How to do Division
Division of big numbers is done by Long Division Method
We will understand the concept with the help of examples
3 by 1 digit Division
Divide 736 by 8
Solution
The above question can be written as 736 ÷ 8
Representing the above expression in long division as:
The dividend is always kept inside the symbol
The divisor is always outside the sumbol
Try to divide number 7 with 8
Since 7 is smaller than 8, the division is not possible
On including next digit we get 73
Try dividing 73 with 8 (i.e. 73 ÷ 8 )
we know that:
9 x 8 = 72
9 x 9 = 81
we will take 72 as it is smaller than selected number 73
Subtract 72 from 73
In the above figure you can see
⟹ 9 is part of quotient (Since we are taking 9 x 8 = 72)
⟹ 01 is remainder (as 73 – 72 = 01)
Include next digit of dividend (number 6)
we know that:
8 x 2 = 16
Include 2 as part of Quotient
and subtract 16 with 16
You can see here remainder is 0, so the division is complete
From the above calculation we now know that
736 ÷ 8 = 92
It means that if we divide 736 number into group of 8, we will get total of 92 groups
4 by 2 digit Division
Divide 1035 by 23
Solution
The problem can be expressed as 1035 ÷ 23
Representing the expression in the form of long division
Divide First number of divided (which is 1)
Since 1 is smaller than 23 (1 < 23), division is not possible
Include the next number 0 to make number 10
Again 10 is less than 23 (10 < 23), division is not possible
Include next number 3 to make 103
Try dividing 103 by 23
We know that:
23 x 4 = 92
23 x 5 = 115
Here 115 is larger than 103
So we select 92 (23 x 4)
⟹ 4 is written in quotient
⟹ when we subtract 103 – 92 = 11 i
Now 11 is left which is not divisible by 23
Include next digit ( number 5) of the dividend
Now we have to divide 115 with 23
We know that
23 x 5 = 115
Include 5 as a part of quotient
And Subtract 115 with 115
You can see that remainder is 0, so division is complete
And we get 45 as final quotient
So 1035 ÷ 23 = 45
It means if we divide 1035 into group of 23, we will get total of 45 groups
Example 02
Divide 1030 by 32
Solution
The above problem can be expressed as (1030 ÷ 32)
Representing the expression in the form of long division
Let’s divide the first number of dividend (i.e. 1)
Since 1 is smaller than 32 (1 < 32), division is not possible
Now include next number (number 0) to form 10
Again 10 is smaller than 32 (10 < 32), division is not possible
Include next number (digit 3) to form number 103
103 is greater than 32, hence division is possible
we know that
32 x 3 = 96
32 x 4 = 128
Since 128 is larger than 103, we will select 96
⟹ Number 3 is written in quotient
⟹ we subtract 103 – 96 to get 07 as remainder
Now include next number (digit 0) of the dividend to get 70
Again 70 is greater than 32, so division is possible
we know that
32 x 2 = 64
32 x 3 = 96
we will select number 64 (32 x 2)
Here we get
⟹ 32 as quotient
⟹ 06 as remainder
Since there is no number left in dividend, the division process is complete
Here the division 1030 ÷ 32 is leaving remainder 6 at the end. Hence the number 1030 is not fully divisible by 32.
Example 03
Divide 4275 by 45
Solution
The problem can be expressed as 4275 ÷ 45
Divide the first number of dividend ( i.e. 4)
Since 4 is smaller than 45 (4 < 45), division is not possible
Taking the second number of dividend, the number will be 42
Again 42 is less than 45 (42 < 45), the division is not possible
Taking the third number of dividend, the number becomes 427
427 is greater than 45, the division is possible
45 x 9 = 405
45 x 10 = 450
we will take 405 because it is smaller than 427
⟹ we get 9 as quotient
⟹ 22 as remainder
Now we include next number (digit 5) to get 225
we know that
45 x 5 = 225
45 x 6 = 270
we will ignore 270 and take 225
Here we get
⟹ 0 remainder, which means division is complete
⟹ 95 as the final quotient
Hence 4275 ÷ 45 = 95
