785257 ÷ 80 
Our goal is to divide 785257 by 80.

Advancing to step 1:
80 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 80

Going ahead to step 2:
78 divided by 80 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 80

Advancing to step 3:
80 can be fit into 785 9 times, resulting in a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 720 from 785, we get 65.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 80

Step 4:
652 divided by 80 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 98.0
If we take 640 away from 652, we end up with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 80

Let's proceed to step 5:
The number 80 fits into 125 1 times, leaving a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 981.0
If we take 80 away from 125, we end up with 45.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 80

Going ahead to step 6:
80 goes into 457 5 times with a remainder of 57.
Write down 5 as next digit of the result. 
Result so far: 9815.0
The remainder is 57 after subtracting 400 from 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
570 divided by 80 is 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 9815.7
If we subtract 560 from 570, we get 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 8:
If we divide 100 by 80, we get 1 and a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 9815.71
Subtracting 80 from 100 leaves us 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.

Let's proceed to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 9815.712
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.

Going ahead to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9815.7125
If we take 400 away from 400, 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.

Moving on to step 11:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9815.7125
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.

Moving on to step 12:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9815.7125
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.

Our division results in 9815.7125 with a remaining 0.0.
