Let's divide 283423 by 18
We want to figure out the number of times 283423 can be divided by 18.

On to step 1:
If we divide 2 by 18, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 18

Step 2:
28 divided by 18 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 18 from 28 to get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 18

Moving on to step 3:
If we divide 103 by 18, we get 5 and a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 90 away from 103, we end up with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 18

Step 4:
The number 18 fits into 134 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 157.0
The remainder is 8 after subtracting 126 from 134.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 18

On to step 5:
18 can be fit into 82 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 1574.0
Subtracting 72 from 82 leaves us with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 18

Let's proceed to step 6:
When dividing 103 by 18, we get 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 15745.0
Subtracting 90 from 103 leaves us 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.

Step 7:
If we divide 130 by 18, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 15745.7
If we take 126 away from 130, 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.

On to step 8:
If we divide 40 by 18, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 15745.72
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing 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: 15745.722
If we subtract 36 from 40, we 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 15745.722 with a remaining 0.0004.
