Advancing to step 6:
When dividing 558 by 878, we get 0 with a remainder of 558.
The number 0 becomes the next digit in our result. 
Result so far: 910.0
The remainder is 558 after subtracting 0 from 558.
Include the next digit (0) from the dividend after 558, then repeat: 5580 / 878

On to step 7:
When dividing 5580 by 878, we get 6 with a remainder of 312.
Write down 6 as next digit of the result. 
Result so far: 9106.0
Subtract 5268 from 5580 to get 312.
Append the next digit (5) from the dividend to 312 and continue with: 3125 / 878

Step 8:
3125 divided by 878 is 3 with a remainder of 491.
The next digit of our result is 3. 
Result so far: 91063.0
The remainder is 491 after subtracting 2634 from 3125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Advancing to step 9:
4910 divided by 878 is 5 with a remainder of 520.
Use 5 as the next digit of our solution. 
Result so far: 91063.5
If we take 4390 away from 4910, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 10:
The number 878 fits into 5200 5 times, leaving a remainder of 810.
The number 5 becomes the next digit in our result. 
Result so far: 91063.55
The remainder is 810 after subtracting 4390 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Our division results in 91063.55 with a remaining 0.81.
