We're dividing 270543 by 15 
Let's see how many times 15 fits into 270543.

On to step 1:
15 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 15

Moving on to step 2:
If we divide 27 by 15, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 15 from 27, we get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 15

Moving on to step 3:
The number 15 fits into 120 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 120 from 120 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 15

Going ahead to step 4:
When dividing 5 by 15, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 180.0
Subtract 0 from 5 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 15

Step 5:
The number 15 fits into 54 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 1803.0
If we take 45 away from 54, we end up with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 15

Let's proceed to step 6:
If we divide 93 by 15, we get 6 and a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 18036.0
Deduct 90 from 93 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
15 goes into 30 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 18036.2
If we take 30 away from 30, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18036.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
15 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18036.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 18036.2, and the remainder is 0.0.
