263230 ÷ 90 
Let's see how many times 90 fits into 263230.

Step 1:
90 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 90

On to step 2:
90 goes into 26 0 times with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 90

Let's proceed to step 3:
If we divide 263 by 90, we get 2 and a remainder of 83.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 180 from 263 to get 83.
Bring next digit (2) of the dividend behind the 83 and repeat the process: 832 / 90

Step 4:
If we divide 832 by 90, we get 9 and a remainder of 22.
The next digit of our result is 9. 
Result so far: 29.0
If we take 810 away from 832, we end up with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 90

On to step 5:
When dividing 223 by 90, we get 2 with a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 292.0
Subtract 180 from 223 to get 43.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 90

Step 6:
90 goes into 430 4 times with a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 2924.0
Deduct 360 from 430 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 7:
When dividing 700 by 90, we get 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 2924.7
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
90 goes into 700 7 times with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 2924.77
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 2924.77 and a remainder of 0.07.
