We look at the division of 68807091 by 80 
Our goal is to divide 68807091 by 80.

Step 1:
6 divided by 80 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 80

Going ahead to step 2:
When dividing 68 by 80, we get 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 80

On to step 3:
80 can be fit into 688 8 times, resulting in a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 640 from 688, we get 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 80

On to step 4:
80 goes into 480 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we subtract 480 from 480, we get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 80

Moving on to step 5:
The number 80 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 860.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 80

On to step 6:
The number 80 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 8600.0
Subtract 0 from 70 to get 70.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 80

Step 7:
The number 80 fits into 709 8 times, leaving a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 86008.0
Subtracting 640 from 709 leaves us with 69.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 80

Going ahead to step 8:
When dividing 691 by 80, we get 8 with a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 860088.0
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.

On to step 9:
The number 80 fits into 510 6 times, leaving a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 860088.6
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.

Moving on to step 10:
When dividing 300 by 80, we get 3 with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 860088.63
Subtracting 240 from 300 leaves us 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 11:
600 divided by 80 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 860088.637
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.

Going ahead to step 12:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 860088.6375
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.

Step 13:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 860088.6375
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.

Step 14:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 860088.6375
Deduct 0 from 0 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.

The final result is 860088.6375 with a remainder of 0.0.
