We look at the division of 995428 by 12 
The aim is to understand the frequency of 12 in 995428.

Moving on to step 1:
If we divide 9 by 12, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 12

Advancing to step 2:
If we divide 99 by 12, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 96 from 99 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 12

Moving on to step 3:
The number 12 fits into 35 2 times, leaving a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 82.0
If we subtract 24 from 35, we get 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 12

Step 4:
The number 12 fits into 114 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 829.0
If we subtract 108 from 114, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 12

Moving on to step 5:
If we divide 62 by 12, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 8295.0
If we subtract 60 from 62, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 12

Let's proceed to step 6:
If we divide 28 by 12, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 82952.0
If we subtract 24 from 28, 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.

Step 7:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 82952.3
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.

Advancing to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 82952.33
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.

After the division, we end up with 82952.33 and a remainder of 0.004.
