56721031 ÷ 20 
We want to divide 56721031 by 20.

Moving on to step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 20

Going ahead to step 2:
When dividing 56 by 20, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 40 from 56 leaves us with 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 20

Let's proceed to step 3:
20 goes into 167 8 times with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 160 from 167 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 20

On to step 4:
The number 20 fits into 72 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 283.0
If we subtract 60 from 72, we get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 20

Going ahead to step 5:
If we divide 121 by 20, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 2836.0
If we subtract 120 from 121, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 20

Let's proceed to step 6:
20 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 28360.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 20

On to step 7:
20 can be fit into 103 5 times, resulting in a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 283605.0
The remainder is 3 after subtracting 100 from 103.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 20

Let's proceed to step 8:
The number 20 fits into 31 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 2836051.0
Subtract 20 from 31 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
20 can be fit into 110 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 2836051.5
The remainder is 10 after subtracting 100 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2836051.55
The remainder is 0 after subtracting 100 from 100.
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 2836051.55 with a remainder of 0.0.
