We're dividing 520330 by 90 
We want to figure out the number of times 520330 can be divided by 90.

Moving on to 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 take 0 away from 5, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 90

Step 2:
When dividing 52 by 90, we get 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 90

Moving on to step 3:
When dividing 520 by 90, we get 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 450 from 520, we get 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 90

On to step 4:
The number 90 fits into 703 7 times, leaving a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtract 630 from 703 to get 73.
Take the next digit (3) from the dividend and append it to 73, then repeat: 733 / 90

Moving on to step 5:
733 divided by 90 is 8 with a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 578.0
Deduct 720 from 733 and we're left with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 90

Going ahead to step 6:
When dividing 130 by 90, we get 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 5781.0
Subtract 90 from 130 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
If we divide 400 by 90, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 5781.4
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
If we divide 400 by 90, we get 4 and a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 5781.44
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 5781.44 with a remainder of 0.04.
