Let's divide 576658 by 90
We want to figure out the number of times 576658 can be divided by 90.

On to step 1:
If we divide 5 by 90, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 90

Advancing to step 2:
When dividing 57 by 90, we get 0 with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Append the next digit (6) from the dividend to 57 and continue with: 576 / 90

On to step 3:
If we divide 576 by 90, we get 6 and a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 540 from 576 leaves us with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 90

Moving on to step 4:
If we divide 366 by 90, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtract 360 from 366 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 90

Step 5:
90 can be fit into 65 0 times, resulting in a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 640.0
If we take 0 away from 65, we end up with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 90

Step 6:
The number 90 fits into 658 7 times, leaving a remainder of 28.
The next digit of our result is 7. 
Result so far: 6407.0
Deduct 630 from 658 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
90 can be fit into 280 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 6407.3
The remainder is 10 after subtracting 270 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 90, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 6407.31
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 90, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 6407.311
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 6407.311 with a remainder of 0.001.
