We look at the division of 163155 by 20 
Our goal is to divide 163155 by 20.

Let's proceed to step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 20

Moving on to step 2:
When dividing 16 by 20, we get 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 20

Let's proceed to step 3:
163 divided by 20 is 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 160 away from 163, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 20

Moving on to step 4:
31 divided by 20 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 11 after subtracting 20 from 31.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 20

Step 5:
If we divide 115 by 20, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 815.0
Deduct 100 from 115 and we're left with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 20

Step 6:
The number 20 fits into 155 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 8157.0
If we subtract 140 from 155, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 8157.7
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8157.75
Subtracting 100 from 100 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:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8157.75
If we subtract 0 from 0, 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.

Let's proceed to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8157.75
If we subtract 0 from 0, 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.

After the division, we end up with 8157.75 and a remainder of 0.0.
