We look at the division of 24015907 by 13 
The aim is to understand the frequency of 13 in 24015907.

Advancing to step 1:
When dividing 2 by 13, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 13

Step 2:
13 goes into 24 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 13 from 24, we get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 13

Moving on to step 3:
If we divide 110 by 13, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 104 from 110 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 13

Going ahead to step 4:
61 divided by 13 is 4 with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
Subtracting 52 from 61 leaves us with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 13

On to step 5:
If we divide 95 by 13, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 1847.0
Subtract 91 from 95 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 13

Advancing to step 6:
If we divide 49 by 13, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 18473.0
The remainder is 10 after subtracting 39 from 49.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 13

On to step 7:
13 goes into 100 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 184737.0
Deduct 91 from 100 and we're left with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 13

Step 8:
13 goes into 97 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 1847377.0
Subtracting 91 from 97 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
When dividing 60 by 13, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 1847377.4
If we subtract 52 from 60, 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.

On to step 10:
If we divide 80 by 13, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 1847377.46
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
13 goes into 20 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1847377.461
Subtracting 13 from 20 leaves us with 7.
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 12:
13 goes into 70 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1847377.4615
Subtracting 65 from 70 leaves us 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.

Moving on to step 13:
50 divided by 13 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 1847377.46153
Subtract 39 from 50 to get 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 14:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 1847377.461538
Subtracting 104 from 110 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 15:
When dividing 60 by 13, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1847377.4615384
Subtracting 52 from 60 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.

Step 16:
If we divide 80 by 13, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 1847377.46153846
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.

The quotient of the division is 1847377.46153846, and the remainder is 2e-09.
