We're dividing 111818 by 18 
The aim is to understand the frequency of 18 in 111818.

Let's proceed to step 1:
The number 18 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 18

Moving on to step 2:
The number 18 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 18

Step 3:
18 can be fit into 111 6 times, resulting in a remainder of 3.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 108 from 111 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 18

Advancing to step 4:
18 can be fit into 38 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we take 36 away from 38, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 18

On to step 5:
18 can be fit into 21 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 621.0
The remainder is 3 after subtracting 18 from 21.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 18

Let's proceed to step 6:
The number 18 fits into 38 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 6212.0
If we take 36 away from 38, we end up 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.

Going ahead to step 7:
The number 18 fits into 20 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 6212.1
Subtracting 18 from 20 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.

Let's proceed to step 8:
If we divide 20 by 18, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 6212.11
If we take 18 away from 20, we end up 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 6212.11 and a remainder of 0.002.
