We look at the division of 415850 by 15 
We want to figure out the number of times 415850 can be divided by 15.

On 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
If we subtract 0 from 4, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 15

Step 2:
41 divided by 15 is 2 with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 11 after subtracting 30 from 41.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 15

Moving on to step 3:
The number 15 fits into 115 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 105 away from 115, we end up with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 15

Let's proceed to step 4:
The number 15 fits into 108 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 277.0
If we take 105 away from 108, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 15

On to step 5:
The number 15 fits into 35 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2772.0
If we take 30 away from 35, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 15

Step 6:
50 divided by 15 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 27723.0
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 27723.3
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 27723.33
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 27723.33, with a leftover of 0.005.
