Let's divide 343140 by 12
The aim is to understand the frequency of 12 in 343140.

Let's proceed to step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 12

Step 2:
34 divided by 12 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 24 from 34 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 12

Step 3:
The number 12 fits into 103 8 times, leaving a remainder of 7.
The next digit of our result is 8. 
Result so far: 28.0
Subtracting 96 from 103 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 12

Moving on to step 4:
The number 12 fits into 71 5 times, leaving a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 285.0
If we take 60 away from 71, we end up with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 12

Advancing to step 5:
When dividing 114 by 12, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 2859.0
Subtracting 108 from 114 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 12

Let's proceed to step 6:
12 goes into 60 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 28595.0
If we take 60 away from 60, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28595.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28595.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 28595.0 with a balance of 0.0.
