42574499 ÷ 990 
We're looking to find how many times 990 goes into 42574499.

On to step 1:
990 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 990

Moving on to step 2:
If we divide 42 by 990, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 990

Step 3:
990 goes into 425 0 times with a remainder of 425.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 425 after subtracting 0 from 425.
Bring next digit (7) of the dividend behind the 425 and repeat the process: 4257 / 990

Step 4:
The number 990 fits into 4257 4 times, leaving a remainder of 297.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3960 from 4257 to get 297.
Fetch the next digit (4) from the dividend, attach it to 297 and continue: 2974 / 990

Advancing to step 5:
990 can be fit into 2974 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we subtract 2970 from 2974, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 990

Let's proceed to step 6:
When dividing 44 by 990, we get 0 with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 430.0
If we subtract 0 from 44, we get 44.
Take the next digit (9) from the dividend and append it to 44, then repeat: 449 / 990

Going ahead to step 7:
990 goes into 449 0 times with a remainder of 449.
Write down 0 as next digit of the result. 
Result so far: 4300.0
Subtract 0 from 449 to get 449.
Bring next digit (9) of the dividend behind the 449 and repeat the process: 4499 / 990

Going ahead to step 8:
When dividing 4499 by 990, we get 4 with a remainder of 539.
The next digit of our result is 4. 
Result so far: 43004.0
The remainder is 539 after subtracting 3960 from 4499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Moving on to step 9:
If we divide 5390 by 990, we get 5 and a remainder of 440.
Write down 5 as next digit of the result. 
Result so far: 43004.5
If we subtract 4950 from 5390, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 10:
The number 990 fits into 4400 4 times, leaving a remainder of 440.
Use 4 as the next digit of our solution. 
Result so far: 43004.54
Subtract 3960 from 4400 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 11:
990 goes into 4400 4 times with a remainder of 440.
Write down 4 as next digit of the result. 
Result so far: 43004.544
If we take 3960 away from 4400, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final result is 43004.544 with a remainder of 0.044.
