We look at the division of 272069 by 13 
The aim is to understand the frequency of 13 in 272069.

Going ahead to step 1:
The number 13 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 13

Let's proceed to step 2:
If we divide 27 by 13, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 1 after subtracting 26 from 27.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 13

Moving on to step 3:
When dividing 12 by 13, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 12, we end up with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 13

Going ahead to step 4:
If we divide 120 by 13, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
Subtract 117 from 120 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 13

Going ahead to step 5:
36 divided by 13 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2092.0
Deduct 26 from 36 and we're left with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 13

Step 6:
The number 13 fits into 109 8 times, leaving a remainder of 5.
The next digit of our result is 8. 
Result so far: 20928.0
Subtract 104 from 109 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 13 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 20928.3
Subtracting 39 from 50 leaves us 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.

Let's proceed to step 8:
110 divided by 13 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 20928.38
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
When dividing 60 by 13, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 20928.384
Subtract 52 from 60 to 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.

Let's proceed to step 10:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 20928.3846
If we take 78 away from 80, we end up 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.

Let's proceed to step 11:
13 goes into 20 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 20928.38461
The remainder is 7 after subtracting 13 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
If we divide 70 by 13, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 20928.384615
Deduct 65 from 70 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
13 can be fit into 50 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 20928.3846153
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
13 can be fit into 110 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 20928.38461538
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 20928.38461538, with a leftover of 6e-09.
