19812 divided by 20 
We want to divide 19812 by 20.

Advancing to step 1:
1 divided by 20 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 20

Going ahead to step 2:
20 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 20

Advancing to step 3:
When dividing 198 by 20, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 180 away from 198, we end up with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 20

On to step 4:
The number 20 fits into 181 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 99.0
Deduct 180 from 181 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 20

On to step 5:
The number 20 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 990.0
If we subtract 0 from 12, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 6:
The number 20 fits into 120 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 990.6
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.

Step 7:
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: 990.6
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.

Moving on to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 990.6
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 990.6 and a remainder of 0.0.
