We look at the division of 406798 by 15 
Let's see how many times 15 fits into 406798.

Going ahead to step 1:
When dividing 4 by 15, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 15

Going ahead to step 2:
The number 15 fits into 40 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 30 from 40 to get 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 15

Advancing to step 3:
If we divide 106 by 15, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 105 from 106, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 15

Moving on to step 4:
17 divided by 15 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 271.0
The remainder is 2 after subtracting 15 from 17.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 15

Moving on to step 5:
The number 15 fits into 29 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 2711.0
If we take 15 away from 29, we end up with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 15

On to step 6:
148 divided by 15 is 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 27119.0
If we take 135 away from 148, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
The number 15 fits into 130 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 27119.8
If we subtract 120 from 130, we 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:
15 goes into 100 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 27119.86
The remainder is 10 after subtracting 90 from 100.
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:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 27119.866
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.

The final result is 27119.866 with a remainder of 0.001.
