We look at the division of 40075976 by 990 
We want to figure out the number of times 40075976 can be divided by 990.

Moving on to step 1:
The number 990 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 990

Advancing to step 2:
40 divided by 990 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 990

Let's proceed to step 3:
When dividing 400 by 990, we get 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 400, we end up with 400.
Take the next digit (7) from the dividend and append it to 400, then repeat: 4007 / 990

Advancing to step 4:
990 can be fit into 4007 4 times, resulting in a remainder of 47.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 47 after subtracting 3960 from 4007.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 990

Moving on to step 5:
990 can be fit into 475 0 times, resulting in a remainder of 475.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we subtract 0 from 475, we get 475.
Bring next digit (9) of the dividend behind the 475 and repeat the process: 4759 / 990

Advancing to step 6:
990 goes into 4759 4 times with a remainder of 799.
Record the quotient 4 as the next digit in the result. 
Result so far: 404.0
Subtracting 3960 from 4759 leaves us with 799.
Grab the next digit (7) from the dividend, add it to 799, then carry on: 7997 / 990

Going ahead to step 7:
7997 divided by 990 is 8 with a remainder of 77.
Record the quotient 8 as the next digit in the result. 
Result so far: 4048.0
If we take 7920 away from 7997, we end up with 77.
Append the next digit (6) from the dividend to 77 and continue with: 776 / 990

On to step 8:
990 can be fit into 776 0 times, resulting in a remainder of 776.
Use 0 as the next digit of our solution. 
Result so far: 40480.0
If we subtract 0 from 776, we get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Moving on to step 9:
The number 990 fits into 7760 7 times, leaving a remainder of 830.
Record the quotient 7 as the next digit in the result. 
Result so far: 40480.7
Subtract 6930 from 7760 to get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Let's proceed to step 10:
If we divide 8300 by 990, we get 8 and a remainder of 380.
The next digit of our result is 8. 
Result so far: 40480.78
If we take 7920 away from 8300, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
If we divide 3800 by 990, we get 3 and a remainder of 830.
The next digit of our result is 3. 
Result so far: 40480.783
The remainder is 830 after subtracting 2970 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Step 12:
990 goes into 8300 8 times with a remainder of 380.
Put 8 as the next digit of the answer. 
Result so far: 40480.7838
Subtracting 7920 from 8300 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 13:
When dividing 3800 by 990, we get 3 with a remainder of 830.
Put 3 as the next digit of the answer. 
Result so far: 40480.78383
Subtracting 2970 from 3800 leaves us with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Going ahead to step 14:
If we divide 8300 by 990, we get 8 and a remainder of 380.
Put 8 as the next digit of the answer. 
Result so far: 40480.783838
If we subtract 7920 from 8300, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 15:
990 goes into 3800 3 times with a remainder of 830.
Put 3 as the next digit of the answer. 
Result so far: 40480.7838383
If we subtract 2970 from 3800, we get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Advancing to step 16:
8300 divided by 990 is 8 with a remainder of 380.
Put 8 as the next digit of the answer. 
Result so far: 40480.78383838
Deduct 7920 from 8300 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 40480.78383838 with a remainder of 3.8e-07.
