We look at the division of 20561720 by 957 
We're looking to find how many times 957 goes into 20561720.

On to step 1:
If we divide 2 by 957, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 957

Let's proceed to step 2:
If we divide 20 by 957, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 957

Going ahead to step 3:
The number 957 fits into 205 0 times, leaving a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 205 after subtracting 0 from 205.
Append the next digit (6) from the dividend to 205 and continue with: 2056 / 957

On to step 4:
The number 957 fits into 2056 2 times, leaving a remainder of 142.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1914 from 2056, we get 142.
Take the next digit (1) from the dividend and append it to 142, then repeat: 1421 / 957

Step 5:
1421 divided by 957 is 1 with a remainder of 464.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 464 after subtracting 957 from 1421.
Append the next digit (7) from the dividend to 464 and continue with: 4647 / 957

On to step 6:
957 goes into 4647 4 times with a remainder of 819.
The number 4 becomes the next digit in our result. 
Result so far: 214.0
Subtract 3828 from 4647 to get 819.
Take the next digit (2) from the dividend and append it to 819, then repeat: 8192 / 957

Step 7:
The number 957 fits into 8192 8 times, leaving a remainder of 536.
Use 8 as the next digit of our solution. 
Result so far: 2148.0
If we take 7656 away from 8192, we end up with 536.
Fetch the next digit (0) from the dividend, attach it to 536 and continue: 5360 / 957

On to step 8:
957 goes into 5360 5 times with a remainder of 575.
The number 5 becomes the next digit in our result. 
Result so far: 21485.0
The remainder is 575 after subtracting 4785 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

On to step 9:
If we divide 5750 by 957, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 21485.6
Deduct 5742 from 5750 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
The number 957 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 21485.6
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
957 goes into 800 0 times with a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 21485.6
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final result is 21485.6 with a remainder of 0.08.
