Let's divide 199287 by 20
We want to divide 199287 by 20.

On to step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 20

Advancing to step 2:
20 can be fit into 19 0 times, resulting in a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 20

Advancing to step 3:
199 divided by 20 is 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 180 from 199 and we're left with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 20

On to step 4:
If we divide 192 by 20, we get 9 and a remainder of 12.
The next digit of our result is 9. 
Result so far: 99.0
Subtracting 180 from 192 leaves us with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 20

Let's proceed to step 5:
If we divide 128 by 20, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 996.0
If we take 120 away from 128, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 20

Advancing to step 6:
When dividing 87 by 20, we get 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 9964.0
The remainder is 7 after subtracting 80 from 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
When dividing 70 by 20, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 9964.3
If we take 60 away from 70, we end up 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.

Step 8:
100 divided by 20 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 9964.35
Deduct 100 from 100 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 9:
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: 9964.35
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.

On to step 10:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9964.35
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 9964.35 and a remainder of 0.0.
