We're dividing 791605 by 20 
Our goal is to divide 791605 by 20.

On to step 1:
7 divided by 20 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 20

Advancing to step 2:
The number 20 fits into 79 3 times, leaving a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 60 from 79 leaves us with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 20

Going ahead to step 3:
If we divide 191 by 20, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 11 after subtracting 180 from 191.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 20

On to step 4:
116 divided by 20 is 5 with a remainder of 16.
The next digit of our result is 5. 
Result so far: 395.0
Subtracting 100 from 116 leaves us with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 20

Going ahead to step 5:
If we divide 160 by 20, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 3958.0
Subtract 160 from 160 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 20

Moving on to step 6:
20 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 39580.0
Deduct 0 from 5 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 20, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 39580.2
Deduct 40 from 50 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.

Step 8:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 39580.25
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.

Advancing to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39580.25
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.

On to step 10:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39580.25
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.

After the division, we end up with 39580.25 and a remainder of 0.0.
