We look at the division of 392187 by 18 
We want to figure out the number of times 392187 can be divided by 18.

On to step 1:
If we divide 3 by 18, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 18

Advancing to step 2:
18 can be fit into 39 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 36 from 39 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 18

Let's proceed to step 3:
32 divided by 18 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 14 after subtracting 18 from 32.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 18

Step 4:
141 divided by 18 is 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 217.0
The remainder is 15 after subtracting 126 from 141.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 18

Step 5:
The number 18 fits into 158 8 times, leaving a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 2178.0
If we take 144 away from 158, we end up with 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 18

Going ahead to step 6:
If we divide 147 by 18, we get 8 and a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 21788.0
The remainder is 3 after subtracting 144 from 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 18, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 21788.1
Subtracting 18 from 30 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
120 divided by 18 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 21788.16
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
18 can be fit into 120 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 21788.166
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 21788.166 with a balance of 0.0012.
