We're dividing 766170 by 80 
We're looking to find how many times 80 goes into 766170.

Let's proceed to step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 80

Let's proceed to step 2:
The number 80 fits into 76 0 times, leaving a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 80

On to step 3:
When dividing 766 by 80, we get 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 720 from 766 and we're left with 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 80

Step 4:
The number 80 fits into 461 5 times, leaving a remainder of 61.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
The remainder is 61 after subtracting 400 from 461.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 80

Moving on to step 5:
617 divided by 80 is 7 with a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 957.0
If we subtract 560 from 617, we get 57.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 80

Moving on to step 6:
If we divide 570 by 80, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 9577.0
Subtracting 560 from 570 leaves us 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.

Let's proceed to step 7:
When dividing 100 by 80, we get 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 9577.1
If we take 80 away from 100, 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.

Step 8:
200 divided by 80 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 9577.12
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 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9577.125
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9577.125
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.

Step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9577.125
Subtract 0 from 0 to 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.

In conclusion, the division gives 9577.125 with a balance of 0.0.
