On to step 4:
When dividing 8878 by 990, we get 8 with a remainder of 958.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 7920 away from 8878, we end up with 958.
Append the next digit (8) from the dividend to 958 and continue with: 9588 / 990

Going ahead to step 5:
When dividing 9588 by 990, we get 9 with a remainder of 678.
Use 9 as the next digit of our solution. 
Result so far: 89.0
The remainder is 678 after subtracting 8910 from 9588.
Take the next digit (0) from the dividend and append it to 678, then repeat: 6780 / 990

On to step 6:
The number 990 fits into 6780 6 times, leaving a remainder of 840.
The number 6 becomes the next digit in our result. 
Result so far: 896.0
Subtract 5940 from 6780 to get 840.
Bring next digit (9) of the dividend behind the 840 and repeat the process: 8409 / 990

On to step 7:
990 can be fit into 8409 8 times, resulting in a remainder of 489.
Use 8 as the next digit of our solution. 
Result so far: 8968.0
If we take 7920 away from 8409, we end up with 489.
Include the next digit (9) from the dividend after 489, then repeat: 4899 / 990

On to step 8:
If we divide 4899 by 990, we get 4 and a remainder of 939.
Write down 4 as next digit of the result. 
Result so far: 89684.0
If we take 3960 away from 4899, we end up with 939.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9390, and continue the process.

On to step 9:
9390 divided by 990 is 9 with a remainder of 480.
Write down 9 as next digit of the result. 
Result so far: 89684.9
Subtracting 8910 from 9390 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 10:
If we divide 4800 by 990, we get 4 and a remainder of 840.
Put 4 as the next digit of the answer. 
Result so far: 89684.94
The remainder is 840 after subtracting 3960 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Let's proceed to step 11:
8400 divided by 990 is 8 with a remainder of 480.
The next digit of our result is 8. 
Result so far: 89684.948
If we take 7920 away from 8400, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 12:
If we divide 4800 by 990, we get 4 and a remainder of 840.
Record the quotient 4 as the next digit in the result. 
Result so far: 89684.9484
Subtracting 3960 from 4800 leaves us with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Step 13:
If we divide 8400 by 990, we get 8 and a remainder of 480.
Write down 8 as next digit of the result. 
Result so far: 89684.94848
Deduct 7920 from 8400 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
990 goes into 4800 4 times with a remainder of 840.
The next digit of our result is 4. 
Result so far: 89684.948484
The remainder is 840 after subtracting 3960 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 15:
When dividing 8400 by 990, we get 8 with a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 89684.9484848
Subtracting 7920 from 8400 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.
