We divide 10812 by 20
Let's see how many times 20 fits into 10812.

Moving on to step 1:
1 divided by 20 is 0 with 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.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 20

Step 2:
The number 20 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 20

Going ahead to step 3:
20 can be fit into 108 5 times, resulting in a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 100 from 108, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 20

On to step 4:
When dividing 81 by 20, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 54.0
Subtracting 80 from 81 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 20

Going ahead to step 5:
When dividing 12 by 20, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 540.0
If we take 0 away from 12, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 6:
20 goes into 120 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 540.6
If we subtract 120 from 120, 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.

Advancing to step 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 540.6
The remainder is 0 after subtracting 0 from 0.
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: 540.6
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.

The final result is 540.6 with a remainder of 0.0.
