We look at the division of 862925 by 12 
The aim is to understand the frequency of 12 in 862925.

Advancing 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
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 12

Step 2:
86 divided by 12 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 84 away from 86, we end up with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 12

Advancing to step 3:
The number 12 fits into 22 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 12 from 22, we get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 12

On to step 4:
12 goes into 109 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 719.0
If we take 108 away from 109, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 12

Step 5:
When dividing 12 by 12, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 7191.0
If we take 12 away from 12, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 12

Advancing to step 6:
12 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 71910.0
If we subtract 0 from 5, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
12 can be fit into 50 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 71910.4
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
12 goes into 20 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 71910.41
Subtracting 12 from 20 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.

Moving on to step 9:
80 divided by 12 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 71910.416
Subtracting 72 from 80 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.

Moving on to step 10:
80 divided by 12 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 71910.4166
If we take 72 away from 80, we end up 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.

The final outcome is 71910.4166, with a leftover of 8e-05.
