742268 divided by 12 
The aim is to understand the frequency of 12 in 742268.

Advancing to step 1:
12 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 12

Let's proceed to step 2:
If we divide 74 by 12, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 72 away from 74, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 12

On to step 3:
12 can be fit into 22 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we subtract 12 from 22, we get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 12

Let's proceed to step 4:
If we divide 102 by 12, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 618.0
Subtract 96 from 102 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 12

Let's proceed to step 5:
When dividing 66 by 12, we get 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 6185.0
Subtracting 60 from 66 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 12

Step 6:
12 goes into 68 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 61855.0
Subtracting 60 from 68 leaves us 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.

Let's proceed to step 7:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 61855.6
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.

Let's proceed to step 8:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 61855.66
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 61855.66 with a remaining 0.008.
