We're dividing 40175047 by 990 
We want to figure out the number of times 40175047 can be divided by 990.

Going ahead to step 1:
990 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 990

Let's proceed to step 2:
When dividing 40 by 990, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 990

Going ahead to step 3:
990 can be fit into 401 0 times, resulting in a remainder of 401.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 401 leaves us with 401.
Grab the next digit (7) from the dividend, add it to 401, then carry on: 4017 / 990

Let's proceed to step 4:
990 can be fit into 4017 4 times, resulting in a remainder of 57.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 57 after subtracting 3960 from 4017.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 990

Advancing to step 5:
The number 990 fits into 575 0 times, leaving a remainder of 575.
The next digit of our result is 0. 
Result so far: 40.0
The remainder is 575 after subtracting 0 from 575.
Bring next digit (0) of the dividend behind the 575 and repeat the process: 5750 / 990

Step 6:
The number 990 fits into 5750 5 times, leaving a remainder of 800.
The number 5 becomes the next digit in our result. 
Result so far: 405.0
Subtracting 4950 from 5750 leaves us with 800.
Take the next digit (4) from the dividend and append it to 800, then repeat: 8004 / 990

On to step 7:
990 can be fit into 8004 8 times, resulting in a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 4058.0
Deduct 7920 from 8004 and we're left with 84.
Append the next digit (7) from the dividend to 84 and continue with: 847 / 990

Moving on to step 8:
If we divide 847 by 990, we get 0 and a remainder of 847.
Write down 0 as next digit of the result. 
Result so far: 40580.0
The remainder is 847 after subtracting 0 from 847.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8470, and continue the process.

Step 9:
If we divide 8470 by 990, we get 8 and a remainder of 550.
Record the quotient 8 as the next digit in the result. 
Result so far: 40580.8
The remainder is 550 after subtracting 7920 from 8470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 10:
If we divide 5500 by 990, we get 5 and a remainder of 550.
The next digit of our result is 5. 
Result so far: 40580.85
Deduct 4950 from 5500 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 11:
When dividing 5500 by 990, we get 5 with a remainder of 550.
The next digit of our result is 5. 
Result so far: 40580.855
The remainder is 550 after subtracting 4950 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

The final result is 40580.855 with a remainder of 0.055.
