892438 ÷ 12 
The aim is to understand the frequency of 12 in 892438.

Step 1:
12 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 12

Going ahead to step 2:
When dividing 89 by 12, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 84 from 89, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 12

Let's proceed to step 3:
When dividing 52 by 12, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtract 48 from 52 to get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 12

Step 4:
12 can be fit into 44 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 743.0
The remainder is 8 after subtracting 36 from 44.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 12

Step 5:
If we divide 83 by 12, we get 6 and a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 7436.0
The remainder is 11 after subtracting 72 from 83.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 12

Step 6:
The number 12 fits into 118 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 74369.0
Deduct 108 from 118 and we're left with 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:
12 can be fit into 100 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 74369.8
Subtract 96 from 100 to 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.

On to step 8:
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: 74369.83
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.

Moving on to step 9:
40 divided by 12 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 74369.833
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.

The final result is 74369.833 with a remainder of 0.0004.
