We divide 771328 by 80
Let's see how many times 80 fits into 771328.

On to step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 80

On to step 2:
If we divide 77 by 80, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 80

Let's proceed to step 3:
If we divide 771 by 80, we get 9 and a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 51 after subtracting 720 from 771.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 80

Going ahead to step 4:
The number 80 fits into 513 6 times, leaving a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we subtract 480 from 513, we get 33.
Append the next digit (2) from the dividend to 33 and continue with: 332 / 80

Let's proceed to step 5:
If we divide 332 by 80, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 964.0
If we take 320 away from 332, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 80

Going ahead to step 6:
80 goes into 128 1 times with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 9641.0
The remainder is 48 after subtracting 80 from 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
The number 80 fits into 480 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 9641.6
The remainder is 0 after subtracting 480 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9641.6
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.

Let's proceed to step 9:
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: 9641.6
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.

The final outcome is 9641.6, with a leftover of 0.0.
