We look at the division of 24112731 by 12 
The aim is to understand the frequency of 12 in 24112731.

Advancing to step 1:
The number 12 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 12

Moving on to step 2:
12 can be fit into 24 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 24 from 24 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 12

Let's proceed to step 3:
When dividing 1 by 12, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 12

Let's proceed to step 4:
The number 12 fits into 11 0 times, leaving a remainder of 11.
The next digit of our result is 0. 
Result so far: 200.0
If we subtract 0 from 11, we get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 12

Going ahead to step 5:
12 can be fit into 112 9 times, resulting in a remainder of 4.
The next digit of our result is 9. 
Result so far: 2009.0
The remainder is 4 after subtracting 108 from 112.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 12

Let's proceed to step 6:
If we divide 47 by 12, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 20093.0
If we subtract 36 from 47, we get 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 12

Let's proceed to step 7:
113 divided by 12 is 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 200939.0
Deduct 108 from 113 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 12

Step 8:
If we divide 51 by 12, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 2009394.0
If we subtract 48 from 51, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
If we divide 30 by 12, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2009394.2
The remainder is 6 after subtracting 24 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2009394.25
Deduct 60 from 60 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2009394.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2009394.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2009394.25 with a remainder of 0.0.
