We divide 878711 by 80
We want to figure out the number of times 878711 can be divided by 80.

Step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 80

On to step 2:
80 goes into 87 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 7 after subtracting 80 from 87.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 80

Moving on to step 3:
When dividing 78 by 80, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 78, we end up with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 80

Moving on to step 4:
When dividing 787 by 80, we get 9 with a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 109.0
The remainder is 67 after subtracting 720 from 787.
Append the next digit (1) from the dividend to 67 and continue with: 671 / 80

On to step 5:
80 goes into 671 8 times with a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 1098.0
If we subtract 640 from 671, we get 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 80

Step 6:
80 can be fit into 311 3 times, resulting in a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 10983.0
Subtract 240 from 311 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
If we divide 710 by 80, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 10983.8
The remainder is 70 after subtracting 640 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
80 goes into 700 8 times with a remainder of 60.
The next digit of our result is 8. 
Result so far: 10983.88
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 10983.88 and a remainder of 0.06.
