We look at the division of 379208 by 18 
The aim is to understand the frequency of 18 in 379208.

Let's proceed to step 1:
18 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 18

Advancing to step 2:
37 divided by 18 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 1 after subtracting 36 from 37.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 18

Moving on to step 3:
The number 18 fits into 19 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 18 from 19 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 18

Let's proceed to step 4:
18 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 210.0
If we subtract 0 from 12, we get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 18

Going ahead to step 5:
120 divided by 18 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 2106.0
If we take 108 away from 120, we end up with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 18

Going ahead to step 6:
If we divide 128 by 18, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 21067.0
Deduct 126 from 128 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.

Moving on to step 7:
If we divide 20 by 18, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 21067.1
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.

Moving on to step 8:
If we divide 20 by 18, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 21067.11
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.

The final outcome is 21067.11, with a leftover of 0.002.
