Let's divide 300028 by 12
The aim is to understand the frequency of 12 in 300028.

Let's proceed to step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 12

Step 2:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 24 away from 30, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 12

Step 3:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 60 from 60 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 12

Going ahead to step 4:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 250.0
Subtract 0 from 0 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 12

Let's proceed to step 5:
12 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 2500.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 12

On to step 6:
12 can be fit into 28 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 25002.0
Subtract 24 from 28 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.

Advancing to step 7:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 25002.3
Subtracting 36 from 40 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.

Advancing to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 25002.33
If we subtract 36 from 40, we 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.

The final result is 25002.33 with a remainder of 0.004.
