574 divided by 12 
The aim is to understand the frequency of 12 in 574.

Let's proceed to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 12

Let's proceed to step 2:
If we divide 57 by 12, we get 4 and a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 48 from 57, we get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 12

On to step 3:
12 goes into 94 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtract 84 from 94 to 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 4:
12 goes into 100 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 47.8
If we take 96 away from 100, we end up 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.

On to step 5:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 47.83
Subtract 36 from 40 to 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.

Moving on to step 6:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 47.833
Subtract 36 from 40 to 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.

In conclusion, the division gives 47.833 with a balance of 0.0004.
