275405 ÷ 90 
We're looking to find how many times 90 goes into 275405.

Going ahead to step 1:
2 divided by 90 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 90

Moving on to step 2:
If we divide 27 by 90, we get 0 and a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 90

Advancing to step 3:
90 goes into 275 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 270 from 275 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 90

Going ahead to step 4:
90 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 54, we end up with 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 90

Advancing to step 5:
The number 90 fits into 540 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 306.0
The remainder is 0 after subtracting 540 from 540.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 90

Advancing to step 6:
If we divide 5 by 90, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 3060.0
Subtract 0 from 5 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
90 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 3060.0
Subtract 0 from 50 to 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.

Going ahead to step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 3060.05
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.

Going ahead to step 9:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3060.055
The remainder is 50 after subtracting 450 from 500.
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 result is 3060.055 with a remainder of 0.005.
