785989 ÷ 80 
Our goal is to divide 785989 by 80.

Let's proceed to step 1:
The number 80 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 80

Advancing to step 2:
If we divide 78 by 80, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 80

On to step 3:
The number 80 fits into 785 9 times, leaving a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 720 from 785, we get 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 80

Step 4:
80 goes into 659 8 times with a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 98.0
Subtracting 640 from 659 leaves us with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 80

Advancing to step 5:
When dividing 198 by 80, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 982.0
Deduct 160 from 198 and we're left with 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 80

Advancing to step 6:
389 divided by 80 is 4 with a remainder of 69.
The next digit of our result is 4. 
Result so far: 9824.0
Subtract 320 from 389 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
The number 80 fits into 690 8 times, leaving a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 9824.8
If we subtract 640 from 690, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 9824.86
The remainder is 20 after subtracting 480 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
80 goes into 200 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 9824.862
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9824.8625
Subtracting 400 from 400 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.

Going ahead to step 11:
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: 9824.8625
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.

On to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9824.8625
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.

The final result is 9824.8625 with a remainder of 0.0.
