Let's divide 415904 by 18
We're looking to find how many times 18 goes into 415904.

Going ahead to step 1:
When dividing 4 by 18, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 18

On to step 2:
18 goes into 41 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 36 from 41 leaves us with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 18

On to step 3:
If we divide 55 by 18, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 54 from 55 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 18

Step 4:
The number 18 fits into 19 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 231.0
Subtracting 18 from 19 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 18

Moving on to step 5:
18 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2310.0
If we take 0 away from 10, we end up with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 18

Advancing to step 6:
104 divided by 18 is 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 23105.0
Subtract 90 from 104 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
The number 18 fits into 140 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 23105.7
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
The number 18 fits into 140 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 23105.77
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 23105.77 with a remainder of 0.014.
