We look at the division of 55233539 by 12 
The aim is to understand the frequency of 12 in 55233539.

Let's proceed to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 12

Let's proceed to step 2:
12 goes into 55 4 times with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 48 from 55 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 12

Moving on to step 3:
The number 12 fits into 72 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we take 72 away from 72, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 12

Let's proceed to step 4:
The number 12 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 460.0
If we subtract 0 from 3, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 12

Let's proceed to step 5:
33 divided by 12 is 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 4602.0
If we subtract 24 from 33, we get 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 12

On to step 6:
95 divided by 12 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 46027.0
The remainder is 11 after subtracting 84 from 95.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 12

Advancing to step 7:
12 can be fit into 113 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 460279.0
If we subtract 108 from 113, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 12

Let's proceed to step 8:
When dividing 59 by 12, we get 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 4602794.0
If we take 48 away from 59, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
12 goes into 110 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 4602794.9
Subtracting 108 from 110 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 12, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 4602794.91
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 4602794.916
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 4602794.9166
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 4602794.9166 and a remainder of 8e-05.
