236116 divided by 18 
The aim is to understand the frequency of 18 in 236116.

Advancing to step 1:
The number 18 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 18

Let's proceed to step 2:
The number 18 fits into 23 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 5 after subtracting 18 from 23.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 18

Let's proceed to step 3:
When dividing 56 by 18, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 54 from 56 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 18

Going ahead to step 4:
21 divided by 18 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 131.0
The remainder is 3 after subtracting 18 from 21.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 18

Moving on to step 5:
31 divided by 18 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1311.0
Subtract 18 from 31 to get 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 18

Step 6:
18 goes into 136 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 13117.0
Subtracting 126 from 136 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 18, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 13117.5
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 18 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 13117.55
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 13117.55, with a leftover of 0.01.
