We look at the division of 406719 by 15 
We want to figure out the number of times 406719 can be divided by 15.

On to step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 15

Advancing to step 2:
15 can be fit into 40 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 30 from 40 leaves us with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 15

Advancing to step 3:
106 divided by 15 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 105 from 106 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 15

On to step 4:
When dividing 17 by 15, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 271.0
If we subtract 15 from 17, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 15

Going ahead to step 5:
21 divided by 15 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 2711.0
The remainder is 6 after subtracting 15 from 21.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 15

Advancing to step 6:
15 goes into 69 4 times with a remainder of 9.
The next digit of our result is 4. 
Result so far: 27114.0
Subtract 60 from 69 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
15 goes into 90 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 27114.6
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.

Let's proceed to step 8:
15 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 27114.6
If we subtract 0 from 0, 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.

Advancing to step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 27114.6
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 27114.6 and a remainder of 0.0.
