We look at the division of 393576 by 18 
Our goal is to divide 393576 by 18.

Let's proceed to step 1:
18 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 18

Step 2:
If we divide 39 by 18, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 36 from 39 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 18

Advancing to step 3:
If we divide 33 by 18, we get 1 and a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 18 from 33 leaves us with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 18

Going ahead to step 4:
18 can be fit into 155 8 times, resulting in a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 218.0
The remainder is 11 after subtracting 144 from 155.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 18

Let's proceed to step 5:
18 goes into 117 6 times with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 2186.0
If we take 108 away from 117, we end up with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 18

Step 6:
The number 18 fits into 96 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 21865.0
If we subtract 90 from 96, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 21865.3
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 21865.33
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 21865.33 with a remaining 0.006.
