We look at the division of 25914 by 65 
The aim is to understand the frequency of 65 in 25914.

Going ahead to step 1:
When dividing 2 by 65, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 65

Let's proceed to step 2:
When dividing 25 by 65, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 65

Advancing to step 3:
When dividing 259 by 65, we get 3 with a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 195 from 259 leaves us with 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 65

On to step 4:
641 divided by 65 is 9 with a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Deduct 585 from 641 and we're left with 56.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 65

Advancing to step 5:
If we divide 564 by 65, we get 8 and a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 398.0
Subtract 520 from 564 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 6:
65 goes into 440 6 times with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 398.6
Subtract 390 from 440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
65 goes into 500 7 times with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 398.67
Subtract 455 from 500 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
450 divided by 65 is 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 398.676
Subtract 390 from 450 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
The number 65 fits into 600 9 times, leaving a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 398.6769
Deduct 585 from 600 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
When dividing 150 by 65, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 398.67692
The remainder is 20 after subtracting 130 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
65 goes into 200 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 398.676923
If we take 195 away from 200, we end up 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 12:
65 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 398.676923
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
The number 65 fits into 500 7 times, leaving a remainder of 45.
The next digit of our result is 7. 
Result so far: 398.67692307
Subtracting 455 from 500 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 398.67692307, with a leftover of 4.5e-08.
