We look at the division of 31535 by 20 
We want to divide 31535 by 20.

Let's proceed to step 1:
20 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 20

Let's proceed to step 2:
31 divided by 20 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 20 from 31 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 20

Going ahead to step 3:
20 goes into 115 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 100 from 115, we get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 20

Advancing to step 4:
20 can be fit into 153 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 157.0
Deduct 140 from 153 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 20

On to step 5:
When dividing 135 by 20, we get 6 with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 1576.0
If we take 120 away from 135, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 6:
150 divided by 20 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 1576.7
If we subtract 140 from 150, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 1576.75
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.

Moving on to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1576.75
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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1576.75
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.

The final result is 1576.75 with a remainder of 0.0.
