We divide 409240 by 15
We're looking to find how many times 15 goes into 409240.

Moving on to step 1:
4 divided by 15 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 15

Moving on to step 2:
15 goes into 40 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 30 from 40 and we're left with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 15

Let's proceed to step 3:
15 goes into 109 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtracting 105 from 109 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 15

Let's proceed to step 4:
15 goes into 42 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 272.0
Subtract 30 from 42 to get 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 15

Advancing to step 5:
The number 15 fits into 124 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 2728.0
The remainder is 4 after subtracting 120 from 124.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 15

On to step 6:
15 goes into 40 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 27282.0
The remainder is 10 after subtracting 30 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 27282.6
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 27282.66
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 27282.66, and the remainder is 0.01.
