Let's divide 788631 by 80
We're looking to find how many times 80 goes into 788631.

On to step 1:
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: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 80

Going ahead to step 2:
If we divide 78 by 80, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 80

Let's proceed to step 3:
80 can be fit into 788 9 times, resulting in a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 720 from 788, we get 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 80

Advancing to step 4:
686 divided by 80 is 8 with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Subtract 640 from 686 to get 46.
Grab the next digit (3) from the dividend, add it to 46, then carry on: 463 / 80

Let's proceed to step 5:
If we divide 463 by 80, we get 5 and a remainder of 63.
Use 5 as the next digit of our solution. 
Result so far: 985.0
Deduct 400 from 463 and we're left with 63.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 80

On to step 6:
When dividing 631 by 80, we get 7 with a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 9857.0
If we take 560 away from 631, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 7:
80 can be fit into 710 8 times, resulting in a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 9857.8
If we take 640 away from 710, we end up 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.

Let's proceed to step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 9857.88
Subtract 640 from 700 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 9857.88 with a remainder of 0.06.
