We divide 347856 by 18
The aim is to understand the frequency of 18 in 347856.

Going ahead to step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 18

Let's proceed to step 2:
When dividing 34 by 18, we get 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 18 from 34 to get 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 18

Advancing to step 3:
18 goes into 167 9 times with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 162 from 167 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 18

On to step 4:
18 goes into 58 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 193.0
If we subtract 54 from 58, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 18

Moving on to step 5:
18 can be fit into 45 2 times, resulting in a remainder of 9.
The next digit of our result is 2. 
Result so far: 1932.0
Subtract 36 from 45 to get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 18

Step 6:
If we divide 96 by 18, we get 5 and a remainder of 6.
The next digit of our result is 5. 
Result so far: 19325.0
Subtract 90 from 96 to 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.

Let's proceed to step 7:
If we divide 60 by 18, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 19325.3
If we subtract 54 from 60, 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.

Going ahead to step 8:
18 can be fit into 60 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 19325.33
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.

The final result is 19325.33 with a remainder of 0.006.
