We're dividing 793149 by 20 
We want to figure out the number of times 793149 can be divided by 20.

Going ahead to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 20

Moving on to step 2:
20 goes into 79 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 60 from 79 to get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 20

Advancing to step 3:
If we divide 193 by 20, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 180 from 193 to get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 20

On to step 4:
The number 20 fits into 131 6 times, leaving a remainder of 11.
The next digit of our result is 6. 
Result so far: 396.0
Deduct 120 from 131 and we're left with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 20

Going ahead to step 5:
20 can be fit into 114 5 times, resulting in a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 3965.0
Subtracting 100 from 114 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 20

Moving on to step 6:
149 divided by 20 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 39657.0
Deduct 140 from 149 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
90 divided by 20 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 39657.4
If we take 80 away from 90, 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.

Moving on to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 39657.45
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39657.45
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.

Let's proceed to step 10:
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: 39657.45
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.

The final outcome is 39657.45, with a leftover of 0.0.
