63121240 ÷ 5 
We want to divide 63121240 by 5.

Advancing to step 1:
The number 5 fits into 6 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 5 from 6, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 5

Going ahead to step 2:
13 divided by 5 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 10 from 13, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 5

On to step 3:
5 goes into 31 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
If we take 30 away from 31, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 5

On to step 4:
12 divided by 5 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 1262.0
Subtract 10 from 12 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 5

Moving on to step 5:
21 divided by 5 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 12624.0
The remainder is 1 after subtracting 20 from 21.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 5

On to step 6:
5 goes into 12 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 126242.0
If we subtract 10 from 12, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 5

Moving on to step 7:
When dividing 24 by 5, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 1262424.0
Subtract 20 from 24 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 5

On to step 8:
When dividing 40 by 5, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 12624248.0
If we subtract 40 from 40, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12624248.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
5 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12624248.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 12624248.0 with a remainder of 0.0.
