We're dividing 393012 by 20 
Our goal is to divide 393012 by 20.

Step 1:
20 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 20

On to step 2:
20 can be fit into 39 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 20 from 39 leaves us with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 20

Let's proceed to step 3:
193 divided by 20 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 180 from 193 leaves us with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 20

Advancing to step 4:
130 divided by 20 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 196.0
If we subtract 120 from 130, we get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 20

Going ahead to step 5:
The number 20 fits into 101 5 times, leaving a remainder of 1.
The next digit of our result is 5. 
Result so far: 1965.0
The remainder is 1 after subtracting 100 from 101.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 20

Moving on to step 6:
When dividing 12 by 20, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 19650.0
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.

Going ahead to step 7:
If we divide 120 by 20, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 19650.6
Subtracting 120 from 120 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 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19650.6
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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19650.6
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.

Our division results in 19650.6 with a remaining 0.0.
