Let's divide 575749 by 90
Let's see how many times 90 fits into 575749.

Step 1:
90 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 90

Going ahead to step 2:
90 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 90

Let's proceed to step 3:
90 can be fit into 575 6 times, resulting in a remainder of 35.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 540 from 575 to get 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 90

Moving on to step 4:
357 divided by 90 is 3 with a remainder of 87.
Write down 3 as next digit of the result. 
Result so far: 63.0
If we subtract 270 from 357, we get 87.
Include the next digit (4) from the dividend after 87, then repeat: 874 / 90

Going ahead to step 5:
90 can be fit into 874 9 times, resulting in a remainder of 64.
The next digit of our result is 9. 
Result so far: 639.0
The remainder is 64 after subtracting 810 from 874.
Append the next digit (9) from the dividend to 64 and continue with: 649 / 90

Advancing to step 6:
The number 90 fits into 649 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 6397.0
Subtracting 630 from 649 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
The number 90 fits into 190 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 6397.2
The remainder is 10 after subtracting 180 from 190.
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:
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: 6397.21
If we subtract 90 from 100, we 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.

Moving on to step 9:
The number 90 fits into 100 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 6397.211
Deduct 90 from 100 and we're left with 10.
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 outcome is 6397.211, with a leftover of 0.001.
