789491 ÷ 80 
Our goal is to divide 789491 by 80.

Advancing to step 1:
80 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 80

On to step 2:
78 divided by 80 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 80

On to step 3:
789 divided by 80 is 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 720 from 789 and we're left with 69.
Bring next digit (4) of the dividend behind the 69 and repeat the process: 694 / 80

Moving on to step 4:
When dividing 694 by 80, we get 8 with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 98.0
Subtract 640 from 694 to get 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 80

Step 5:
When dividing 549 by 80, we get 6 with a remainder of 69.
The next digit of our result is 6. 
Result so far: 986.0
Subtracting 480 from 549 leaves us with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 80

Going ahead to step 6:
The number 80 fits into 691 8 times, leaving a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 9868.0
The remainder is 51 after subtracting 640 from 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
When dividing 510 by 80, we get 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 9868.6
Subtract 480 from 510 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 9868.63
The remainder is 60 after subtracting 240 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
The number 80 fits into 600 7 times, leaving a remainder of 40.
The next digit of our result is 7. 
Result so far: 9868.637
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.

Step 10:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 9868.6375
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.

Let's proceed to step 11:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9868.6375
The remainder is 0 after subtracting 0 from 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 12:
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: 9868.6375
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.

After the division, we end up with 9868.6375 and a remainder of 0.0.
