We're dividing 75105508 by 990 
We're looking to find how many times 990 goes into 75105508.

Step 1:
7 divided by 990 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 990

Going ahead to step 2:
990 can be fit into 75 0 times, resulting in a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Take the next digit (1) from the dividend and append it to 75, then repeat: 751 / 990

Step 3:
751 divided by 990 is 0 with a remainder of 751.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 751 to get 751.
Append the next digit (0) from the dividend to 751 and continue with: 7510 / 990

On to step 4:
990 can be fit into 7510 7 times, resulting in a remainder of 580.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 6930 from 7510 and we're left with 580.
Fetch the next digit (5) from the dividend, attach it to 580 and continue: 5805 / 990

Let's proceed to step 5:
990 can be fit into 5805 5 times, resulting in a remainder of 855.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we subtract 4950 from 5805, we get 855.
Take the next digit (5) from the dividend and append it to 855, then repeat: 8555 / 990

Let's proceed to step 6:
If we divide 8555 by 990, we get 8 and a remainder of 635.
Put 8 as the next digit of the answer. 
Result so far: 758.0
The remainder is 635 after subtracting 7920 from 8555.
Include the next digit (0) from the dividend after 635, then repeat: 6350 / 990

Advancing to step 7:
6350 divided by 990 is 6 with a remainder of 410.
Write down 6 as next digit of the result. 
Result so far: 7586.0
The remainder is 410 after subtracting 5940 from 6350.
Include the next digit (8) from the dividend after 410, then repeat: 4108 / 990

On to step 8:
If we divide 4108 by 990, we get 4 and a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 75864.0
If we take 3960 away from 4108, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 9:
990 goes into 1480 1 times with a remainder of 490.
The next digit of our result is 1. 
Result so far: 75864.1
The remainder is 490 after subtracting 990 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 10:
The number 990 fits into 4900 4 times, leaving a remainder of 940.
Write down 4 as next digit of the result. 
Result so far: 75864.14
Subtract 3960 from 4900 to get 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Going ahead to step 11:
9400 divided by 990 is 9 with a remainder of 490.
Write down 9 as next digit of the result. 
Result so far: 75864.149
Subtracting 8910 from 9400 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 12:
990 can be fit into 4900 4 times, resulting in a remainder of 940.
Put 4 as the next digit of the answer. 
Result so far: 75864.1494
Deduct 3960 from 4900 and we're left with 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Advancing to step 13:
990 goes into 9400 9 times with a remainder of 490.
Write down 9 as next digit of the result. 
Result so far: 75864.14949
Subtract 8910 from 9400 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 14:
990 goes into 4900 4 times with a remainder of 940.
Use 4 as the next digit of our solution. 
Result so far: 75864.149494
If we subtract 3960 from 4900, we get 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Let's proceed to step 15:
The number 990 fits into 9400 9 times, leaving a remainder of 490.
Record the quotient 9 as the next digit in the result. 
Result so far: 75864.1494949
If we subtract 8910 from 9400, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 16:
When dividing 4900 by 990, we get 4 with a remainder of 940.
Use 4 as the next digit of our solution. 
Result so far: 75864.14949494
If we subtract 3960 from 4900, we get 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

In conclusion, the division gives 75864.14949494 with a balance of 9.4e-07.
