Subtract 0 from 8 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 990

Going ahead to step 2:
84 divided by 990 is 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Take the next digit (2) from the dividend and append it to 84, then repeat: 842 / 990

Going ahead to step 3:
When dividing 842 by 990, we get 0 with a remainder of 842.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 842 leaves us with 842.
Include the next digit (2) from the dividend after 842, then repeat: 8422 / 990

Step 4:
The number 990 fits into 8422 8 times, leaving a remainder of 502.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 502 after subtracting 7920 from 8422.
Fetch the next digit (4) from the dividend, attach it to 502 and continue: 5024 / 990

Advancing to step 5:
When dividing 5024 by 990, we get 5 with a remainder of 74.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtracting 4950 from 5024 leaves us with 74.
Include the next digit (1) from the dividend after 74, then repeat: 741 / 990

On to step 6:
990 goes into 741 0 times with a remainder of 741.
Put 0 as the next digit of the answer. 
Result so far: 850.0
The remainder is 741 after subtracting 0 from 741.
Bring next digit (8) of the dividend behind the 741 and repeat the process: 7418 / 990

Step 7:
990 can be fit into 7418 7 times, resulting in a remainder of 488.
Write down 7 as next digit of the result. 
Result so far: 8507.0
Subtract 6930 from 7418 to get 488.
Take the next digit (6) from the dividend and append it to 488, then repeat: 4886 / 990

Step 8:
990 goes into 4886 4 times with a remainder of 926.
Write down 4 as next digit of the result. 
Result so far: 85074.0
The remainder is 926 after subtracting 3960 from 4886.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9260, and continue the process.

Step 9:
990 goes into 9260 9 times with a remainder of 350.
The number 9 becomes the next digit in our result. 
Result so far: 85074.9
If we subtract 8910 from 9260, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 10:
When dividing 3500 by 990, we get 3 with a remainder of 530.
Use 3 as the next digit of our solution. 
Result so far: 85074.93
If we take 2970 away from 3500, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 11:
5300 divided by 990 is 5 with a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 85074.935
Subtract 4950 from 5300 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 12:
990 goes into 3500 3 times with a remainder of 530.
Record the quotient 3 as the next digit in the result. 
Result so far: 85074.9353
Deduct 2970 from 3500 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 13:
990 can be fit into 5300 5 times, resulting in a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 85074.93535
The remainder is 350 after subtracting 4950 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 14:
990 can be fit into 3500 3 times, resulting in a remainder of 530.
Write down 3 as next digit of the result. 
Result so far: 85074.935353
If we subtract 2970 from 3500, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 15:
If we divide 5300 by 990, we get 5 and a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 85074.9353535
Subtracting 4950 from 5300 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 16:
The number 990 fits into 3500 3 times, leaving a remainder of 530.
Put 3 as the next digit of the answer. 
Result so far: 85074.93535353
If we take 2970 away from 3500, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.
