We look at the division of 552074 by 12 
The aim is to understand the frequency of 12 in 552074.

Let's proceed to step 1:
5 divided by 12 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 12

Moving on to step 2:
55 divided by 12 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 48 from 55 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 12

Moving on to step 3:
When dividing 72 by 12, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we subtract 72 from 72, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 12

Let's proceed to step 4:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 460.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 12

Advancing to step 5:
12 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 4600.0
If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 12

Going ahead to step 6:
The number 12 fits into 74 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 46006.0
Subtract 72 from 74 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 46006.1
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 46006.16
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 46006.166
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 46006.166 and a remainder of 0.0008.
