We're dividing 242236 by 12 
The aim is to understand the frequency of 12 in 242236.

Step 1:
The number 12 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 12

Let's proceed to step 2:
The number 12 fits into 24 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 24 from 24 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 12

Step 3:
When dividing 2 by 12, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 12

Let's proceed to step 4:
12 can be fit into 22 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 201.0
Deduct 12 from 22 and we're left with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 12

Step 5:
103 divided by 12 is 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 2018.0
Deduct 96 from 103 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 12

Step 6:
12 can be fit into 76 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 20186.0
Subtracting 72 from 76 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
When dividing 40 by 12, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 20186.3
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 20186.33
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 20186.33 and a remainder of 0.004.
