We divide 270138 by 90
We're looking to find how many times 90 goes into 270138.

Going ahead to step 1:
90 goes into 2 0 times with 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 (7) of the dividend behind the 2 and repeat the process: 27 / 90

Let's proceed to step 2:
The number 90 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 90

Let's proceed to step 3:
When dividing 270 by 90, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 270 from 270 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 90

Moving on to step 4:
1 divided by 90 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 90

Moving on to step 5:
13 divided by 90 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 300.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 90

On to step 6:
If we divide 138 by 90, we get 1 and a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 3001.0
If we take 90 away from 138, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
If we divide 480 by 90, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 3001.5
The remainder is 30 after subtracting 450 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
If we divide 300 by 90, we get 3 and a remainder of 30.
The next digit of our result is 3. 
Result so far: 3001.53
The remainder is 30 after subtracting 270 from 300.
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 9:
The number 90 fits into 300 3 times, leaving a remainder of 30.
The next digit of our result is 3. 
Result so far: 3001.533
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.

After the division, we end up with 3001.533 and a remainder of 0.003.
