We divide 691759 by 80
Our goal is to divide 691759 by 80.

Advancing to step 1:
If we divide 6 by 80, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 80

Going ahead to step 2:
80 can be fit into 69 0 times, resulting in a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 80

Let's proceed to step 3:
80 goes into 691 8 times with a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 640 from 691 to get 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 80

Let's proceed to step 4:
When dividing 517 by 80, we get 6 with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 37 after subtracting 480 from 517.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 80

Step 5:
The number 80 fits into 375 4 times, leaving a remainder of 55.
Put 4 as the next digit of the answer. 
Result so far: 864.0
Subtract 320 from 375 to get 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 80

Moving on to step 6:
559 divided by 80 is 6 with a remainder of 79.
Put 6 as the next digit of the answer. 
Result so far: 8646.0
Deduct 480 from 559 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 7:
If we divide 790 by 80, we get 9 and a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 8646.9
Deduct 720 from 790 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
80 goes into 700 8 times with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 8646.98
Deduct 640 from 700 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.

On 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: 8646.987
If we take 560 away from 600, we end up 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.

Going ahead to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8646.9875
If we subtract 400 from 400, 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.

Advancing to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8646.9875
If we take 0 away from 0, 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.

Advancing to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8646.9875
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 8646.9875 with a remainder of 0.0.
