We look at the division of 637562 by 20 
Our goal is to divide 637562 by 20.

On to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 20

Going ahead to step 2:
The number 20 fits into 63 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 60 from 63, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 20

Moving on to step 3:
If we divide 37 by 20, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 20 from 37 to get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 20

On to step 4:
20 goes into 175 8 times with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 318.0
Deduct 160 from 175 and we're left with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 20

Let's proceed to step 5:
If we divide 156 by 20, we get 7 and a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 3187.0
If we take 140 away from 156, we end up with 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 20

Let's proceed to step 6:
If we divide 162 by 20, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 31878.0
If we subtract 160 from 162, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
20 can be fit into 20 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 31878.1
Deduct 20 from 20 and we're left 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.

On to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31878.1
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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31878.1
Subtract 0 from 0 to 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.

After the division, we end up with 31878.1 and a remainder of 0.0.
