Let's divide 489113 by 90
We want to figure out the number of times 489113 can be divided by 90.

Let's proceed to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 90

Going ahead to step 2:
90 can be fit into 48 0 times, resulting in a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 90

Step 3:
The number 90 fits into 489 5 times, leaving a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 450 from 489 to get 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 90

Going ahead to step 4:
When dividing 391 by 90, we get 4 with a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtract 360 from 391 to get 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 90

Advancing to step 5:
90 can be fit into 311 3 times, resulting in a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 543.0
If we take 270 away from 311, we end up with 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 90

Going ahead to step 6:
90 goes into 413 4 times with a remainder of 53.
The next digit of our result is 4. 
Result so far: 5434.0
If we take 360 away from 413, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
530 divided by 90 is 5 with a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 5434.5
The remainder is 80 after subtracting 450 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
If we divide 800 by 90, we get 8 and a remainder of 80.
The next digit of our result is 8. 
Result so far: 5434.58
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 5434.588
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 5434.588 with a remainder of 0.008.
