We're dividing 540552 by 15 
Let's see how many times 15 fits into 540552.

Going ahead to step 1:
15 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 15

Moving on to step 2:
The number 15 fits into 54 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 45 away from 54, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 15

On to step 3:
15 can be fit into 90 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 90 from 90, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 15

On to step 4:
15 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 360.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 15

Going ahead to step 5:
The number 15 fits into 55 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3603.0
Deduct 45 from 55 and we're left with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 15

Let's proceed to step 6:
15 can be fit into 102 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 36036.0
Subtracting 90 from 102 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
If we divide 120 by 15, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 36036.8
If we subtract 120 from 120, we 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.

Step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 36036.8
Subtracting 0 from 0 leaves us 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.

Going ahead to step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36036.8
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.

After the division, we end up with 36036.8 and a remainder of 0.0.
