We're dividing 540540 by 15 
Let's see how many times 15 fits into 540540.

Let's proceed to step 1:
The number 15 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 15

Step 2:
15 can be fit into 54 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 45 from 54 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 15

On to step 3:
When dividing 90 by 15, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 36.0
The remainder is 0 after subtracting 90 from 90.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 15

Going ahead to step 4:
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: 360.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 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: 3603.0
Deduct 45 from 54 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 15

Going ahead to step 6:
90 divided by 15 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 36036.0
The remainder is 0 after subtracting 90 from 90.
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 7:
If we divide 0 by 15, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 36036.0
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.

On to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36036.0
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 36036.0 and a remainder of 0.0.
