Let's divide 260088 by 90
Our goal is to divide 260088 by 90.

On to step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 90

On to step 2:
The number 90 fits into 26 0 times, leaving a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 90

Going ahead to step 3:
90 can be fit into 260 2 times, resulting in a remainder of 80.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 180 from 260 leaves us with 80.
Grab the next digit (0) from the dividend, add it to 80, then carry on: 800 / 90

Step 4:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 720 from 800 and we're left with 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 90

Step 5:
808 divided by 90 is 8 with a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 288.0
If we take 720 away from 808, we end up with 88.
Bring next digit (8) of the dividend behind the 88 and repeat the process: 888 / 90

Step 6:
90 can be fit into 888 9 times, resulting in a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 2889.0
The remainder is 78 after subtracting 810 from 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 7:
90 can be fit into 780 8 times, resulting in a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 2889.8
If we take 720 away from 780, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
90 can be fit into 600 6 times, resulting in a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 2889.86
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
If we divide 600 by 90, we get 6 and a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 2889.866
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 2889.866 with a remaining 0.006.
