We divide 584980 by 90
We're looking to find how many times 90 goes into 584980.

Going ahead to step 1:
When dividing 5 by 90, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 90

Moving on to step 2:
When dividing 58 by 90, we get 0 with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 90

Advancing to step 3:
The number 90 fits into 584 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 540 from 584 to get 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 90

On to step 4:
If we divide 449 by 90, we get 4 and a remainder of 89.
Use 4 as the next digit of our solution. 
Result so far: 64.0
The remainder is 89 after subtracting 360 from 449.
Fetch the next digit (8) from the dividend, attach it to 89 and continue: 898 / 90

Step 5:
The number 90 fits into 898 9 times, leaving a remainder of 88.
Use 9 as the next digit of our solution. 
Result so far: 649.0
If we take 810 away from 898, we end up with 88.
Bring next digit (0) of the dividend behind the 88 and repeat the process: 880 / 90

Moving on to step 6:
If we divide 880 by 90, we get 9 and a remainder of 70.
The next digit of our result is 9. 
Result so far: 6499.0
If we subtract 810 from 880, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 7:
90 goes into 700 7 times with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 6499.7
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
90 goes into 700 7 times with a remainder of 70.
The next digit of our result is 7. 
Result so far: 6499.77
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 6499.77 with a balance of 0.07.
