We divide 423266 by 13
The aim is to understand the frequency of 13 in 423266.

Step 1:
When dividing 4 by 13, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 13

Let's proceed to step 2:
If we divide 42 by 13, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 39 from 42, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 13

Advancing to step 3:
33 divided by 13 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Deduct 26 from 33 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 13

Let's proceed to step 4:
13 can be fit into 72 5 times, resulting in a remainder of 7.
The next digit of our result is 5. 
Result so far: 325.0
If we take 65 away from 72, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 13

On to step 5:
The number 13 fits into 76 5 times, leaving a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 3255.0
The remainder is 11 after subtracting 65 from 76.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 13

Let's proceed to step 6:
When dividing 116 by 13, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 32558.0
If we take 104 away from 116, 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.

Going ahead 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: 32558.9
Deduct 117 from 120 and we're left 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.

Advancing to step 8:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 32558.92
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.

Let's proceed to step 9:
When dividing 40 by 13, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 32558.923
If we take 39 away from 40, we end up with 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:
If we divide 10 by 13, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 32558.923
Deduct 0 from 10 and we're left 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.

Moving on to step 11:
13 can be fit into 100 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 32558.92307
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
When dividing 90 by 13, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 32558.923076
Deduct 78 from 90 and we're left 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.

On to step 13:
13 can be fit into 120 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 32558.9230769
If we subtract 117 from 120, we 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:
30 divided by 13 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 32558.92307692
If we subtract 26 from 30, we get 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 32558.92307692 with a remainder of 4e-09.
