We divide 523238 by 90
We want to figure out the number of times 523238 can be divided by 90.

Step 1:
The number 90 fits into 5 0 times, leaving 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 (2) from the dividend to 5 and continue with: 52 / 90

Going ahead to step 2:
If we divide 52 by 90, we get 0 and a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 90

On to step 3:
If we divide 523 by 90, we get 5 and a remainder of 73.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 450 from 523 to get 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 90

On to step 4:
The number 90 fits into 732 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtracting 720 from 732 leaves us with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 90

Let's proceed to step 5:
90 goes into 123 1 times with a remainder of 33.
The next digit of our result is 1. 
Result so far: 581.0
If we subtract 90 from 123, we get 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 90

Step 6:
The number 90 fits into 338 3 times, leaving a remainder of 68.
The next digit of our result is 3. 
Result so far: 5813.0
Subtract 270 from 338 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
680 divided by 90 is 7 with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 5813.7
Subtract 630 from 680 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5813.75
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
If we divide 500 by 90, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5813.755
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 5813.755, with a leftover of 0.005.
