409246 divided by 15 
We want to figure out the number of times 409246 can be divided by 15.

Advancing to step 1:
4 divided by 15 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 15

Let's proceed to step 2:
The number 15 fits into 40 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 30 away from 40, we end up with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 15

Let's proceed to step 3:
109 divided by 15 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 105 from 109 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 15

On to step 4:
15 can be fit into 42 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 272.0
If we subtract 30 from 42, we get 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 15

On to step 5:
15 can be fit into 124 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 2728.0
If we take 120 away from 124, we end up with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 15

On to step 6:
15 goes into 46 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 27283.0
If we take 45 away from 46, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
15 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 27283.0
Subtract 0 from 10 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.

Advancing to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 27283.06
Subtracting 90 from 100 leaves us 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.

Moving on to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 27283.066
Deduct 90 from 100 and we're left 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 27283.066, and the remainder is 0.001.
