We look at the division of 623955 by 12 
The aim is to understand the frequency of 12 in 623955.

Moving on to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 12

Let's proceed to step 2:
12 can be fit into 62 5 times, resulting in a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 60 from 62 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 12

Moving on to step 3:
12 goes into 23 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we subtract 12 from 23, we get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 12

Let's proceed to step 4:
When dividing 119 by 12, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 519.0
Subtract 108 from 119 to get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 12

Let's proceed to step 5:
12 goes into 115 9 times with a remainder of 7.
The next digit of our result is 9. 
Result so far: 5199.0
If we subtract 108 from 115, we get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 12

Moving on to step 6:
The number 12 fits into 75 6 times, leaving a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 51996.0
Subtracting 72 from 75 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 12 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 51996.2
The remainder is 6 after subtracting 24 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 51996.25
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
12 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 51996.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 51996.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 51996.25 with a balance of 0.0.
