Let's divide 488280 by 90
Let's see how many times 90 fits into 488280.

Moving on to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 90

On to step 2:
90 goes into 48 0 times with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Append the next digit (8) from the dividend to 48 and continue with: 488 / 90

Going ahead to step 3:
90 goes into 488 5 times with a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 450 from 488 to get 38.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 90

On to step 4:
If we divide 382 by 90, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 54.0
If we subtract 360 from 382, we get 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 90

Advancing to step 5:
90 goes into 228 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 542.0
If we take 180 away from 228, we end up with 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 90

Advancing to step 6:
90 can be fit into 480 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 5425.0
If we subtract 450 from 480, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
90 goes into 300 3 times with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 5425.3
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 90, we get 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 5425.33
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 5425.33, and the remainder is 0.03.
