Let's divide 490460 by 90
Let's see how many times 90 fits into 490460.

Moving on to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 90

Step 2:
49 divided by 90 is 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 90

Moving on to step 3:
When dividing 490 by 90, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 450 away from 490, we end up with 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 90

Let's proceed to step 4:
The number 90 fits into 404 4 times, leaving a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we take 360 away from 404, we end up with 44.
Take the next digit (6) from the dividend and append it to 44, then repeat: 446 / 90

Going ahead to step 5:
446 divided by 90 is 4 with a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 544.0
If we subtract 360 from 446, we get 86.
Append the next digit (0) from the dividend to 86 and continue with: 860 / 90

Moving on to step 6:
860 divided by 90 is 9 with a remainder of 50.
The next digit of our result is 9. 
Result so far: 5449.0
If we subtract 810 from 860, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
90 can be fit into 500 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 5449.5
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
500 divided by 90 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 5449.55
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 5449.55 and a remainder of 0.05.
