We look at the division of 771165 by 80 
We want to divide 771165 by 80.

Going ahead to step 1:
If we divide 7 by 80, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 80

Going ahead to step 2:
If we divide 77 by 80, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 80

Going ahead to step 3:
If we divide 771 by 80, we get 9 and a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 720 from 771 to get 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 80

Step 4:
The number 80 fits into 511 6 times, leaving a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we take 480 away from 511, we end up with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 80

On to step 5:
When dividing 316 by 80, we get 3 with a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 963.0
Deduct 240 from 316 and we're left with 76.
Fetch the next digit (5) from the dividend, attach it to 76 and continue: 765 / 80

Step 6:
80 goes into 765 9 times with a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 9639.0
The remainder is 45 after subtracting 720 from 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 7:
80 goes into 450 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 9639.5
The remainder is 50 after subtracting 400 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
When dividing 500 by 80, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 9639.56
If we take 480 away from 500, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 9639.562
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 9639.5625
Subtracting 400 from 400 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.

On to step 11:
80 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: 9639.5625
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.

On to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 9639.5625
If we subtract 0 from 0, we get 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 9639.5625 with a remainder of 0.0.
