Let's divide 866668 by 12
The aim is to understand the frequency of 12 in 866668.

Going ahead to step 1:
12 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 12

Moving on to step 2:
When dividing 86 by 12, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 2 after subtracting 84 from 86.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 12

Let's proceed to step 3:
The number 12 fits into 26 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtracting 24 from 26 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 12

Going ahead to step 4:
26 divided by 12 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 722.0
Subtract 24 from 26 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 12

Let's proceed to step 5:
26 divided by 12 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 7222.0
If we subtract 24 from 26, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 12

Moving on to step 6:
28 divided by 12 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 72222.0
The remainder is 4 after subtracting 24 from 28.
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.
Write down 3 as next digit of the result. 
Result so far: 72222.3
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.

Going ahead to step 8:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 72222.33
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.

The quotient of the division is 72222.33, and the remainder is 0.004.
