Let's divide 7504 by 12
The aim is to understand the frequency of 12 in 7504.

Step 1:
7 divided by 12 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 12

Step 2:
If we divide 75 by 12, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 72 from 75 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 12

Going ahead to step 3:
When dividing 30 by 12, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 62.0
Deduct 24 from 30 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 12

Let's proceed to step 4:
12 goes into 64 5 times with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 625.0
Subtracting 60 from 64 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.

Let's proceed to step 5:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 625.3
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:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 625.33
If we take 36 away from 40, 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.

The final outcome is 625.33, with a leftover of 0.004.
