We look at the division of 772140 by 80 
We want to divide 772140 by 80.

Advancing to step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 80

Going ahead to step 2:
80 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (2) from the dividend and append it to 77, then repeat: 772 / 80

Let's proceed to step 3:
772 divided by 80 is 9 with a remainder of 52.
The next digit of our result is 9. 
Result so far: 9.0
If we take 720 away from 772, we end up with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 80

Advancing to step 4:
80 goes into 521 6 times with a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 41 after subtracting 480 from 521.
Grab the next digit (4) from the dividend, add it to 41, then carry on: 414 / 80

On to step 5:
When dividing 414 by 80, we get 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 965.0
Deduct 400 from 414 and we're left with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 80

Step 6:
When dividing 140 by 80, we get 1 with a remainder of 60.
The next digit of our result is 1. 
Result so far: 9651.0
Deduct 80 from 140 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 7:
If we divide 600 by 80, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 9651.7
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9651.75
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 9:
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: 9651.75
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.

Let's proceed to step 10:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9651.75
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.

After the division, we end up with 9651.75 and a remainder of 0.0.
