We're dividing 789580 by 80 
Our goal is to divide 789580 by 80.

On to step 1:
7 divided by 80 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 80

Advancing to step 2:
80 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 80

Let's proceed to step 3:
80 can be fit into 789 9 times, resulting in a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 720 from 789, we get 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 80

On to step 4:
80 goes into 695 8 times with a remainder of 55.
The next digit of our result is 8. 
Result so far: 98.0
The remainder is 55 after subtracting 640 from 695.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 80

On to step 5:
When dividing 558 by 80, we get 6 with a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 986.0
Deduct 480 from 558 and we're left with 78.
Include the next digit (0) from the dividend after 78, then repeat: 780 / 80

Advancing to step 6:
The number 80 fits into 780 9 times, leaving a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 9869.0
Deduct 720 from 780 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:
80 goes into 600 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 9869.7
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.

Let's proceed to step 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9869.75
Deduct 400 from 400 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 9:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9869.75
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 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9869.75
If we subtract 0 from 0, we 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.

The final result is 9869.75 with a remainder of 0.0.
