We look at the division of 177766 by 12 
The aim is to understand the frequency of 12 in 177766.

Step 1:
12 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 12

On to step 2:
12 can be fit into 17 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 12 from 17 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 12

Step 3:
12 can be fit into 57 4 times, resulting in a remainder of 9.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 48 from 57 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 12

Let's proceed to step 4:
12 can be fit into 97 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 148.0
Subtract 96 from 97 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 12

Step 5:
When dividing 16 by 12, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1481.0
Subtracting 12 from 16 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 12

On to step 6:
If we divide 46 by 12, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 14813.0
Subtract 36 from 46 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
When dividing 100 by 12, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 14813.8
If we subtract 96 from 100, 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.

Going ahead to step 8:
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: 14813.83
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.

Let's proceed to step 9:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 14813.833
If we take 36 away from 40, 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.

After the division, we end up with 14813.833 and a remainder of 0.0004.
