We look at the division of 737392 by 12 
The aim is to understand the frequency of 12 in 737392.

Let's proceed to step 1:
7 divided by 12 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 12

On to step 2:
When dividing 73 by 12, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 1 after subtracting 72 from 73.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 12

Let's proceed to step 3:
12 can be fit into 17 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
The remainder is 5 after subtracting 12 from 17.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 12

Advancing to step 4:
The number 12 fits into 53 4 times, leaving a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 614.0
If we subtract 48 from 53, we get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 12

On to step 5:
12 can be fit into 59 4 times, resulting in a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 6144.0
If we subtract 48 from 59, we get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 12

Step 6:
The number 12 fits into 112 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 61449.0
Deduct 108 from 112 and we're left 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.

Step 7:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 61449.3
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.

Step 8:
40 divided by 12 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 61449.33
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.

Our division results in 61449.33 with a remaining 0.004.
