We look at the division of 494284 by 90 
We want to figure out the number of times 494284 can be divided by 90.

Advancing to step 1:
4 divided by 90 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 90

Let's proceed to step 2:
The number 90 fits into 49 0 times, leaving a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 90

Going ahead to step 3:
494 divided by 90 is 5 with a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 44 after subtracting 450 from 494.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 90

Moving on to step 4:
The number 90 fits into 442 4 times, leaving a remainder of 82.
The next digit of our result is 4. 
Result so far: 54.0
The remainder is 82 after subtracting 360 from 442.
Grab the next digit (8) from the dividend, add it to 82, then carry on: 828 / 90

On to step 5:
828 divided by 90 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 549.0
If we subtract 810 from 828, we get 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 90

On to step 6:
If we divide 184 by 90, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 5492.0
If we take 180 away from 184, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 90 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5492.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
400 divided by 90 is 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 5492.04
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
90 goes into 400 4 times with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 5492.044
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 5492.044 and a remainder of 0.004.
