We look at the division of 216255 by 20 
We want to divide 216255 by 20.

Moving on to step 1:
When dividing 2 by 20, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 20

On to step 2:
20 can be fit into 21 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 20 from 21 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 20

On to step 3:
The number 20 fits into 16 0 times, leaving a remainder of 16.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 20

Going ahead to step 4:
When dividing 162 by 20, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 108.0
Subtract 160 from 162 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 20

Let's proceed to step 5:
When dividing 25 by 20, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1081.0
Subtract 20 from 25 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 20

Moving on to step 6:
20 can be fit into 55 2 times, resulting in a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 10812.0
Subtract 40 from 55 to 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.

Advancing to step 7:
20 can be fit into 150 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 10812.7
Deduct 140 from 150 and we're left with 10.
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 8:
20 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10812.75
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.

On to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10812.75
Deduct 0 from 0 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 10:
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: 10812.75
If we take 0 away from 0, we end up 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.

The final result is 10812.75 with a remainder of 0.0.
