429252 ÷ 12 
The aim is to understand the frequency of 12 in 429252.

Advancing to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 12

On to step 2:
12 can be fit into 42 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 36 from 42 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 12

Advancing to step 3:
69 divided by 12 is 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtract 60 from 69 to get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 12

Going ahead to step 4:
92 divided by 12 is 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 357.0
The remainder is 8 after subtracting 84 from 92.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 12

Moving on to step 5:
12 goes into 85 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 3577.0
The remainder is 1 after subtracting 84 from 85.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 12

Let's proceed to step 6:
12 divided by 12 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 35771.0
Subtract 12 from 12 to get 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 7:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 35771.0
If we subtract 0 from 0, we get 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:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 35771.0
Subtracting 0 from 0 leaves us 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.

In conclusion, the division gives 35771.0 with a balance of 0.0.
