Let's divide 189892 by 12
The aim is to understand the frequency of 12 in 189892.

Step 1:
1 divided by 12 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 12

Let's proceed to step 2:
18 divided by 12 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
If we take 12 away from 18, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 12

Moving on to step 3:
69 divided by 12 is 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 9 after subtracting 60 from 69.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 12

Advancing to step 4:
The number 12 fits into 98 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
If we subtract 96 from 98, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 12

Step 5:
If we divide 29 by 12, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 1582.0
The remainder is 5 after subtracting 24 from 29.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 12

Step 6:
12 can be fit into 52 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 15824.0
If we take 48 away from 52, 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.

Let's proceed to step 7:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 15824.3
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.

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: 15824.33
If we subtract 36 from 40, 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.

The final outcome is 15824.33, with a leftover of 0.004.
