We divide 427585 by 18
We want to figure out the number of times 427585 can be divided by 18.

Moving on to step 1:
The number 18 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 18

Advancing to step 2:
42 divided by 18 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 36 from 42 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 18

Let's proceed to step 3:
18 goes into 67 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 54 from 67 to get 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 18

Let's proceed to step 4:
If we divide 135 by 18, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 237.0
If we subtract 126 from 135, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 18

Moving on to step 5:
When dividing 98 by 18, we get 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 2375.0
If we take 90 away from 98, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 18

Going ahead to step 6:
The number 18 fits into 85 4 times, leaving a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 23754.0
The remainder is 13 after subtracting 72 from 85.
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:
18 can be fit into 130 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 23754.7
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 18 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 23754.72
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
18 goes into 40 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 23754.722
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 23754.722 with a remaining 0.0004.
