499452 divided by 90 
We're looking to find how many times 90 goes into 499452.

Step 1:
4 divided by 90 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 90

Going ahead to step 2:
If we divide 49 by 90, we get 0 and a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 90

Let's proceed to step 3:
499 divided by 90 is 5 with a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 450 from 499 and we're left with 49.
Fetch the next digit (4) from the dividend, attach it to 49 and continue: 494 / 90

Advancing to step 4:
When dividing 494 by 90, we get 5 with a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 55.0
If we subtract 450 from 494, we get 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 90

Step 5:
90 can be fit into 445 4 times, resulting in a remainder of 85.
Put 4 as the next digit of the answer. 
Result so far: 554.0
Subtract 360 from 445 to get 85.
Include the next digit (2) from the dividend after 85, then repeat: 852 / 90

Step 6:
90 can be fit into 852 9 times, resulting in a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 5549.0
Subtract 810 from 852 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
The number 90 fits into 420 4 times, leaving a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 5549.4
If we take 360 away from 420, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 5549.46
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 5549.466
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 5549.466 with a remainder of 0.006.
