575574 divided by 90 
We want to figure out the number of times 575574 can be divided by 90.

Step 1:
The number 90 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 90

Let's proceed to step 2:
57 divided by 90 is 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 90

Step 3:
575 divided by 90 is 6 with a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 540 from 575 to get 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 90

Going ahead to step 4:
The number 90 fits into 355 3 times, leaving a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Subtract 270 from 355 to get 85.
Grab the next digit (7) from the dividend, add it to 85, then carry on: 857 / 90

On to step 5:
When dividing 857 by 90, we get 9 with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 639.0
Subtract 810 from 857 to get 47.
Append the next digit (4) from the dividend to 47 and continue with: 474 / 90

Moving on to step 6:
The number 90 fits into 474 5 times, leaving a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 6395.0
If we subtract 450 from 474, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
90 goes into 240 2 times with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 6395.2
If we take 180 away from 240, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 6395.26
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
If we divide 600 by 90, we get 6 and a remainder of 60.
The next digit of our result is 6. 
Result so far: 6395.266
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 6395.266 with a remainder of 0.006.
