We're dividing 42175 by 18 
We're looking to find how many times 18 goes into 42175.

Step 1:
If we divide 4 by 18, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 18

Moving on 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
If we take 36 away from 42, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 18

Step 3:
If we divide 61 by 18, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 54 away from 61, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 18

Step 4:
18 goes into 77 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 234.0
The remainder is 5 after subtracting 72 from 77.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 18

Let's proceed to step 5:
55 divided by 18 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 2343.0
The remainder is 1 after subtracting 54 from 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 6:
18 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2343.0
If we subtract 0 from 10, 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.

Let's proceed to step 7:
100 divided by 18 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 2343.05
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.

Moving on to step 8:
If we divide 100 by 18, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2343.055
If we subtract 90 from 100, 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.

Our division results in 2343.055 with a remaining 0.001.
