We look at the division of 794979 by 20 
We're looking to find how many times 20 goes into 794979.

On to step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 20

Let's proceed to step 2:
If we divide 79 by 20, we get 3 and a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 60 from 79, we get 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 20

Advancing to step 3:
20 goes into 194 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 180 from 194 and we're left with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 20

Moving on to step 4:
The number 20 fits into 149 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 397.0
The remainder is 9 after subtracting 140 from 149.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 20

Advancing to step 5:
20 can be fit into 97 4 times, resulting in a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 3974.0
Subtracting 80 from 97 leaves us with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 20

Step 6:
20 can be fit into 179 8 times, resulting in a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 39748.0
Deduct 160 from 179 and we're left 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.

Let's proceed to step 7:
20 goes into 190 9 times with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 39748.9
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.

Moving on to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 39748.95
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.

Moving on to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 39748.95
If we take 0 away from 0, 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.

Moving on to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39748.95
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.

The final result is 39748.95 with a remainder of 0.0.
