Let's divide 40845154 by 990
We want to divide 40845154 by 990.

On to step 1:
The number 990 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 990

Advancing to step 2:
990 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 990

Step 3:
990 can be fit into 408 0 times, resulting in a remainder of 408.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 408, we end up with 408.
Append the next digit (4) from the dividend to 408 and continue with: 4084 / 990

Step 4:
990 can be fit into 4084 4 times, resulting in a remainder of 124.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3960 from 4084 and we're left with 124.
Grab the next digit (5) from the dividend, add it to 124, then carry on: 1245 / 990

Moving on to step 5:
990 can be fit into 1245 1 times, resulting in a remainder of 255.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtract 990 from 1245 to get 255.
Append the next digit (1) from the dividend to 255 and continue with: 2551 / 990

Moving on to step 6:
When dividing 2551 by 990, we get 2 with a remainder of 571.
Use 2 as the next digit of our solution. 
Result so far: 412.0
Deduct 1980 from 2551 and we're left with 571.
Grab the next digit (5) from the dividend, add it to 571, then carry on: 5715 / 990

Going ahead to step 7:
The number 990 fits into 5715 5 times, leaving a remainder of 765.
Use 5 as the next digit of our solution. 
Result so far: 4125.0
The remainder is 765 after subtracting 4950 from 5715.
Include the next digit (4) from the dividend after 765, then repeat: 7654 / 990

Advancing to step 8:
If we divide 7654 by 990, we get 7 and a remainder of 724.
The next digit of our result is 7. 
Result so far: 41257.0
Deduct 6930 from 7654 and we're left with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Step 9:
990 goes into 7240 7 times with a remainder of 310.
The next digit of our result is 7. 
Result so far: 41257.7
Subtract 6930 from 7240 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 10:
990 goes into 3100 3 times with a remainder of 130.
Use 3 as the next digit of our solution. 
Result so far: 41257.73
The remainder is 130 after subtracting 2970 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 11:
The number 990 fits into 1300 1 times, leaving a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 41257.731
If we take 990 away from 1300, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 12:
If we divide 3100 by 990, we get 3 and a remainder of 130.
Use 3 as the next digit of our solution. 
Result so far: 41257.7313
If we take 2970 away from 3100, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 13:
When dividing 1300 by 990, we get 1 with a remainder of 310.
The next digit of our result is 1. 
Result so far: 41257.73131
The remainder is 310 after subtracting 990 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 14:
3100 divided by 990 is 3 with a remainder of 130.
Record the quotient 3 as the next digit in the result. 
Result so far: 41257.731313
Subtracting 2970 from 3100 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 15:
When dividing 1300 by 990, we get 1 with a remainder of 310.
Put 1 as the next digit of the answer. 
Result so far: 41257.7313131
If we subtract 990 from 1300, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 16:
If we divide 3100 by 990, we get 3 and a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 41257.73131313
Subtracting 2970 from 3100 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The quotient of the division is 41257.73131313, and the remainder is 1.3e-07.
