We look at the division of 10085655 by 990 
Let's see how many times 990 fits into 10085655.

Advancing to step 1:
990 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 990

Let's proceed to step 2:
When dividing 10 by 990, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 990

Advancing to step 3:
The number 990 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 100 leaves us with 100.
Fetch the next digit (8) from the dividend, attach it to 100 and continue: 1008 / 990

On to step 4:
990 goes into 1008 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 18 after subtracting 990 from 1008.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 990

Let's proceed to step 5:
185 divided by 990 is 0 with a remainder of 185.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 185 leaves us with 185.
Fetch the next digit (6) from the dividend, attach it to 185 and continue: 1856 / 990

Advancing to step 6:
990 can be fit into 1856 1 times, resulting in a remainder of 866.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
If we subtract 990 from 1856, we get 866.
Bring next digit (5) of the dividend behind the 866 and repeat the process: 8665 / 990

Step 7:
When dividing 8665 by 990, we get 8 with a remainder of 745.
Use 8 as the next digit of our solution. 
Result so far: 1018.0
The remainder is 745 after subtracting 7920 from 8665.
Bring next digit (5) of the dividend behind the 745 and repeat the process: 7455 / 990

Going ahead to step 8:
990 goes into 7455 7 times with a remainder of 525.
The number 7 becomes the next digit in our result. 
Result so far: 10187.0
The remainder is 525 after subtracting 6930 from 7455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

On to step 9:
5250 divided by 990 is 5 with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 10187.5
The remainder is 300 after subtracting 4950 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 10:
The number 990 fits into 3000 3 times, leaving a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 10187.53
Subtract 2970 from 3000 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
If we divide 300 by 990, we get 0 and a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 10187.53
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 12:
3000 divided by 990 is 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 10187.5303
If we subtract 2970 from 3000, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
The number 990 fits into 300 0 times, leaving a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 10187.5303
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 14:
990 can be fit into 3000 3 times, resulting in a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 10187.530303
If we subtract 2970 from 3000, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 15:
The number 990 fits into 300 0 times, leaving a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 10187.530303
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 16:
When dividing 3000 by 990, we get 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 10187.53030303
If we take 2970 away from 3000, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 10187.53030303 and a remainder of 3e-08.
