We're dividing 389414 by 18 
Let's see how many times 18 fits into 389414.

Step 1:
The number 18 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 18

Step 2:
18 can be fit into 38 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 36 from 38 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 18

On to step 3:
If we divide 29 by 18, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 18 from 29, we get 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 18

Step 4:
18 can be fit into 114 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
The remainder is 6 after subtracting 108 from 114.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 18

Moving on to step 5:
When dividing 61 by 18, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 2163.0
Deduct 54 from 61 and we're left with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 18

Step 6:
The number 18 fits into 74 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 21634.0
Subtracting 72 from 74 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 18 fits into 20 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 21634.1
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
18 can be fit into 20 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 21634.11
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 21634.11 and a remainder of 0.002.
