307324 ÷ 12 
The aim is to understand the frequency of 12 in 307324.

Moving on to step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 12

Step 2:
30 divided by 12 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 24 away from 30, we end up with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 12

Let's proceed to step 3:
67 divided by 12 is 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 60 away from 67, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 12

Step 4:
73 divided by 12 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 256.0
Subtracting 72 from 73 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 12

Moving on to step 5:
12 goes into 12 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 2561.0
The remainder is 0 after subtracting 12 from 12.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 12

Moving on to step 6:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 25610.0
If we take 0 away from 4, 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.

Going ahead to step 7:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 25610.3
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.

On to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 25610.33
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 25610.33 and a remainder of 0.004.
