We're dividing 255333 by 90 
We're looking to find how many times 90 goes into 255333.

Moving on to step 1:
If we divide 2 by 90, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 90

Moving on to step 2:
The number 90 fits into 25 0 times, leaving a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 90

Going ahead to step 3:
255 divided by 90 is 2 with a remainder of 75.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 75 after subtracting 180 from 255.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 90

Step 4:
When dividing 753 by 90, we get 8 with a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 720 from 753 to get 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 90

Let's proceed to step 5:
The number 90 fits into 333 3 times, leaving a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 283.0
The remainder is 63 after subtracting 270 from 333.
Fetch the next digit (3) from the dividend, attach it to 63 and continue: 633 / 90

Advancing to step 6:
633 divided by 90 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 2837.0
Subtract 630 from 633 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 90 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 2837.0
Subtracting 0 from 30 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.

Going ahead to step 8:
If we divide 300 by 90, we get 3 and a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 2837.03
If we subtract 270 from 300, we 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.

Step 9:
90 goes into 300 3 times with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 2837.033
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 2837.033, with a leftover of 0.003.
