13000815 divided by 65 
The aim is to understand the frequency of 65 in 13000815.

Advancing to step 1:
1 divided by 65 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 65

Moving on to step 2:
When dividing 13 by 65, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 65

Step 3:
130 divided by 65 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 130 from 130, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 65

Step 4:
0 divided by 65 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 65

Advancing to step 5:
The number 65 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 200.0
If we take 0 away from 0, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 65

On to step 6:
When dividing 8 by 65, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 2000.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 65

Advancing to step 7:
81 divided by 65 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 20001.0
Subtract 65 from 81 to get 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 65

Going ahead to step 8:
165 divided by 65 is 2 with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 200012.0
Subtracting 130 from 165 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
When dividing 350 by 65, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 200012.5
Subtracting 325 from 350 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
250 divided by 65 is 3 with a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 200012.53
Subtract 195 from 250 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
550 divided by 65 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 200012.538
The remainder is 30 after subtracting 520 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
300 divided by 65 is 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 200012.5384
The remainder is 40 after subtracting 260 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
65 can be fit into 400 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 200012.53846
If we subtract 390 from 400, we get 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 14:
If we divide 100 by 65, we get 1 and a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 200012.538461
Subtract 65 from 100 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 15:
350 divided by 65 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 200012.5384615
Subtracting 325 from 350 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 16:
If we divide 250 by 65, we get 3 and a remainder of 55.
The next digit of our result is 3. 
Result so far: 200012.53846153
Subtracting 195 from 250 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 200012.53846153 with a remainder of 5.5e-08.
