We look at the division of 886457 by 12 
The aim is to understand the frequency of 12 in 886457.

Going ahead to step 1:
8 divided by 12 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 12

Let's proceed to step 2:
If we divide 88 by 12, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 84 from 88 leaves us with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 12

Moving on to step 3:
46 divided by 12 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
If we subtract 36 from 46, we get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 12

Step 4:
104 divided by 12 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 738.0
If we take 96 away from 104, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 12

Going ahead to step 5:
12 goes into 85 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7387.0
The remainder is 1 after subtracting 84 from 85.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 12

Moving on to step 6:
When dividing 17 by 12, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 73871.0
Subtracting 12 from 17 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
When dividing 50 by 12, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 73871.4
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.

On to step 8:
12 goes into 20 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 73871.41
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 73871.416
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.

Advancing to step 10:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 73871.4166
Subtract 72 from 80 to 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 73871.4166 with a remaining 8e-05.
