488850 ÷ 90 
We want to divide 488850 by 90.

Advancing to step 1:
When dividing 4 by 90, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 90

Step 2:
If we divide 48 by 90, we get 0 and a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 90

Going ahead to step 3:
The number 90 fits into 488 5 times, leaving a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 450 from 488 leaves us with 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 90

Let's proceed to step 4:
90 can be fit into 388 4 times, resulting in a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we take 360 away from 388, we end up with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 90

Advancing to step 5:
When dividing 285 by 90, we get 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 543.0
Deduct 270 from 285 and we're left with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 90

Moving on to step 6:
150 divided by 90 is 1 with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 5431.0
Subtract 90 from 150 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.

Moving on to step 7:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 5431.6
Deduct 540 from 600 and we're left 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.

On to step 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 5431.66
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.

Our division results in 5431.66 with a remaining 0.06.
