We divide 488691 by 90
Let's see how many times 90 fits into 488691.

Let's proceed to step 1:
90 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 90

Let's proceed to step 2:
If we divide 48 by 90, we get 0 and a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 90

Moving on to step 3:
488 divided by 90 is 5 with a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 450 from 488 to get 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 90

Let's proceed to step 4:
90 can be fit into 386 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 54.0
Subtract 360 from 386 to get 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 90

Let's proceed to step 5:
90 goes into 269 2 times with a remainder of 89.
Put 2 as the next digit of the answer. 
Result so far: 542.0
Subtracting 180 from 269 leaves us with 89.
Take the next digit (1) from the dividend and append it to 89, then repeat: 891 / 90

Step 6:
90 can be fit into 891 9 times, resulting in a remainder of 81.
The next digit of our result is 9. 
Result so far: 5429.0
If we subtract 810 from 891, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 7:
90 can be fit into 810 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 5429.9
If we subtract 810 from 810, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 90 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5429.9
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 90, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5429.9
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 5429.9, with a leftover of 0.0.
