We're dividing 413585 by 18 
We're looking to find how many times 18 goes into 413585.

Step 1:
When dividing 4 by 18, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 18

Moving on to step 2:
When dividing 41 by 18, we get 2 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.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 18

Let's proceed to step 3:
53 divided by 18 is 2 with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 17 after subtracting 36 from 53.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 18

Step 4:
When dividing 175 by 18, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 229.0
Subtract 162 from 175 to get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 18

Let's proceed to step 5:
18 goes into 138 7 times with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 2297.0
If we subtract 126 from 138, we get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 18

Advancing to step 6:
When dividing 125 by 18, we get 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 22976.0
Subtracting 108 from 125 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
18 can be fit into 170 9 times, resulting in a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 22976.9
Subtracting 162 from 170 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
80 divided by 18 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 22976.94
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 22976.944
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 22976.944 with a remainder of 0.0008.
