Let's divide 793239 by 20
We want to figure out the number of times 793239 can be divided by 20.

On to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 20

On to step 2:
The number 20 fits into 79 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 60 from 79 to get 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 20

Advancing to step 3:
20 goes into 193 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 39.0
If we take 180 away from 193, we end up with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 20

Advancing to step 4:
The number 20 fits into 132 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 396.0
If we subtract 120 from 132, we get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 20

Step 5:
When dividing 123 by 20, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 3966.0
If we subtract 120 from 123, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 20

Let's proceed to step 6:
When dividing 39 by 20, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 39661.0
If we take 20 away from 39, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
The number 20 fits into 190 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 39661.9
Deduct 180 from 190 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.

Going ahead to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 39661.95
If we take 100 away from 100, 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.

On to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39661.95
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.

Step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39661.95
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.

The final result is 39661.95 with a remainder of 0.0.
