We divide 525542 by 90
We want to figure out the number of times 525542 can be divided by 90.

Step 1:
5 divided by 90 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 90

Step 2:
If we divide 52 by 90, we get 0 and 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.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 90

Advancing to step 3:
525 divided by 90 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 450 from 525 and we're left with 75.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 90

On to step 4:
The number 90 fits into 755 8 times, leaving a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Deduct 720 from 755 and we're left with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 90

Step 5:
When dividing 354 by 90, we get 3 with a remainder of 84.
Use 3 as the next digit of our solution. 
Result so far: 583.0
If we take 270 away from 354, we end up with 84.
Fetch the next digit (2) from the dividend, attach it to 84 and continue: 842 / 90

On to step 6:
90 can be fit into 842 9 times, resulting in a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 5839.0
If we subtract 810 from 842, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
When dividing 320 by 90, we get 3 with a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 5839.3
If we take 270 away from 320, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
90 can be fit into 500 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 5839.35
If we take 450 away from 500, we end up with 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 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 5839.355
If we subtract 450 from 500, we 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 5839.355, with a leftover of 0.005.
