We're dividing 449269 by 13 
The aim is to understand the frequency of 13 in 449269.

Let's proceed to step 1:
4 divided by 13 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 13

Advancing to step 2:
13 can be fit into 44 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 39 from 44 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 13

On to step 3:
If we divide 59 by 13, we get 4 and a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 52 from 59 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 13

Step 4:
The number 13 fits into 72 5 times, leaving a remainder of 7.
The next digit of our result is 5. 
Result so far: 345.0
Subtract 65 from 72 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 13

Moving on to step 5:
13 goes into 76 5 times with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 3455.0
If we take 65 away from 76, we end up with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 13

On to step 6:
13 can be fit into 119 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 34559.0
If we take 117 away from 119, 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.

Advancing to step 7:
20 divided by 13 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 34559.1
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.

Going ahead to step 8:
13 goes into 70 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 34559.15
If we subtract 65 from 70, we 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.

Moving on to step 9:
If we divide 50 by 13, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 34559.153
If we take 39 away from 50, 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.

Going ahead to step 10:
If we divide 110 by 13, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 34559.1538
If we subtract 104 from 110, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
13 goes into 60 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 34559.15384
If we take 52 away from 60, we end up 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.

Moving on to step 12:
80 divided by 13 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 34559.153846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
13 can be fit into 20 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 34559.1538461
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.

Moving on to step 14:
70 divided by 13 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 34559.15384615
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.

The final result is 34559.15384615 with a remainder of 5e-09.
