878856 divided by 80 
We want to figure out the number of times 878856 can be divided by 80.

On to step 1:
8 divided by 80 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 80

Going ahead to step 2:
87 divided by 80 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 80 from 87, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 80

Step 3:
78 divided by 80 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 80

Advancing to step 4:
When dividing 788 by 80, we get 9 with a remainder of 68.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
Deduct 720 from 788 and we're left with 68.
Grab the next digit (5) from the dividend, add it to 68, then carry on: 685 / 80

Step 5:
80 goes into 685 8 times with a remainder of 45.
Use 8 as the next digit of our solution. 
Result so far: 1098.0
If we subtract 640 from 685, we get 45.
Grab the next digit (6) from the dividend, add it to 45, then carry on: 456 / 80

Advancing to step 6:
80 goes into 456 5 times with a remainder of 56.
The next digit of our result is 5. 
Result so far: 10985.0
Deduct 400 from 456 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
The number 80 fits into 560 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 10985.7
If we take 560 away from 560, 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.

Let's proceed to step 8:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10985.7
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 9:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10985.7
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.

The quotient of the division is 10985.7, and the remainder is 0.0.
