575958 divided by 90 
We want to divide 575958 by 90.

Advancing to step 1:
5 divided by 90 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 90

Going ahead to step 2:
90 can be fit into 57 0 times, resulting in a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 90

Let's proceed to step 3:
When dividing 575 by 90, we get 6 with a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 540 from 575, we get 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 90

Step 4:
359 divided by 90 is 3 with a remainder of 89.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Deduct 270 from 359 and we're left with 89.
Bring next digit (5) of the dividend behind the 89 and repeat the process: 895 / 90

Advancing to step 5:
90 goes into 895 9 times with a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 639.0
The remainder is 85 after subtracting 810 from 895.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 90

Advancing to step 6:
858 divided by 90 is 9 with a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 6399.0
Subtract 810 from 858 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
When dividing 480 by 90, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 6399.5
Subtract 450 from 480 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 90, we get 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 6399.53
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
The number 90 fits into 300 3 times, leaving a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 6399.533
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 6399.533, with a leftover of 0.003.
