540144 divided by 65 
The aim is to understand the frequency of 65 in 540144.

Step 1:
65 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 65

Moving on to step 2:
If we divide 54 by 65, we get 0 and a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 65

Advancing to step 3:
540 divided by 65 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 520 from 540 and we're left with 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 65

On to step 4:
201 divided by 65 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 83.0
If we take 195 away from 201, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 65

On to step 5:
The number 65 fits into 64 0 times, leaving a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 830.0
If we subtract 0 from 64, we get 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 65

Going ahead to step 6:
The number 65 fits into 644 9 times, leaving a remainder of 59.
The next digit of our result is 9. 
Result so far: 8309.0
The remainder is 59 after subtracting 585 from 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
The number 65 fits into 590 9 times, leaving a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 8309.9
Deduct 585 from 590 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.

Advancing to step 8:
The number 65 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 8309.9
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.

Let's proceed to step 9:
When dividing 500 by 65, we get 7 with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 8309.907
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.

Let's proceed to step 10:
65 goes into 450 6 times with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 8309.9076
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.

Going ahead to step 11:
The number 65 fits into 600 9 times, leaving a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 8309.90769
Subtract 585 from 600 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
The number 65 fits into 150 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 8309.907692
Subtracting 130 from 150 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
The number 65 fits into 200 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 8309.9076923
The remainder is 5 after subtracting 195 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
65 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 8309.9076923
If we take 0 away from 50, we end up 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.

The final result is 8309.9076923 with a remainder of 5e-08.
