555255 divided by 13 
The aim is to understand the frequency of 13 in 555255.

Going ahead to step 1:
13 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 13

Step 2:
If we divide 55 by 13, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 52 from 55 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 13

Advancing to step 3:
35 divided by 13 is 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 26 from 35, we get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 13

Let's proceed to step 4:
When dividing 92 by 13, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 427.0
If we subtract 91 from 92, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 13

Advancing to step 5:
The number 13 fits into 15 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 4271.0
If we subtract 13 from 15, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 13

Advancing to step 6:
When dividing 25 by 13, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 42711.0
Subtracting 13 from 25 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
If we divide 120 by 13, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 42711.9
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 42711.92
The remainder is 4 after subtracting 26 from 30.
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 9:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 42711.923
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
10 divided by 13 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 42711.923
If we take 0 away from 10, we end up 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.

Step 11:
13 goes into 100 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 42711.92307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
When dividing 90 by 13, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 42711.923076
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
120 divided by 13 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 42711.9230769
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
When dividing 30 by 13, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 42711.92307692
Deduct 26 from 30 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.

The final result is 42711.92307692 with a remainder of 4e-09.
