We're dividing 449452 by 90 
Our goal is to divide 449452 by 90.

On to step 1:
90 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 90

Advancing to step 2:
The number 90 fits into 44 0 times, leaving a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 90

Step 3:
449 divided by 90 is 4 with a remainder of 89.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 360 from 449 leaves us with 89.
Bring next digit (4) of the dividend behind the 89 and repeat the process: 894 / 90

On to step 4:
894 divided by 90 is 9 with a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we subtract 810 from 894, we get 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 90

Advancing to step 5:
90 goes into 845 9 times with a remainder of 35.
The next digit of our result is 9. 
Result so far: 499.0
Subtracting 810 from 845 leaves us with 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 90

Let's proceed to step 6:
90 can be fit into 352 3 times, resulting in a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 4993.0
If we take 270 away from 352, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 7:
When dividing 820 by 90, we get 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 4993.9
Subtract 810 from 820 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
90 can be fit into 100 1 times, resulting in a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 4993.91
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
90 goes into 100 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 4993.911
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 4993.911 and a remainder of 0.001.
