We divide 255730 by 90
We want to divide 255730 by 90.

Step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 90

Let's proceed to step 2:
90 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 90

On to step 3:
90 can be fit into 255 2 times, resulting in a remainder of 75.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 75 after subtracting 180 from 255.
Include the next digit (7) from the dividend after 75, then repeat: 757 / 90

Advancing to step 4:
If we divide 757 by 90, we get 8 and a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtracting 720 from 757 leaves us with 37.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 90

Going ahead to step 5:
90 can be fit into 373 4 times, resulting in a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 284.0
Subtracting 360 from 373 leaves us with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 90

Moving on to step 6:
If we divide 130 by 90, we get 1 and a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 2841.0
If we subtract 90 from 130, 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.

Moving on to step 7:
When dividing 400 by 90, we get 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 2841.4
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:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 2841.44
Subtracting 360 from 400 leaves us with 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 outcome is 2841.44, with a leftover of 0.04.
