We're dividing 751978 by 65 
The aim is to understand the frequency of 65 in 751978.

Step 1:
If we divide 7 by 65, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 65

Going ahead to step 2:
75 divided by 65 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 65 from 75 leaves us with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 65

On to step 3:
When dividing 101 by 65, we get 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 36 after subtracting 65 from 101.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 65

On to step 4:
The number 65 fits into 369 5 times, leaving a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
The remainder is 44 after subtracting 325 from 369.
Take the next digit (7) from the dividend and append it to 44, then repeat: 447 / 65

Advancing to step 5:
447 divided by 65 is 6 with a remainder of 57.
The next digit of our result is 6. 
Result so far: 1156.0
Deduct 390 from 447 and we're left with 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 65

Moving on to step 6:
If we divide 578 by 65, we get 8 and a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 11568.0
If we subtract 520 from 578, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 7:
65 can be fit into 580 8 times, resulting in a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 11568.8
If we take 520 away from 580, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
When dividing 600 by 65, we get 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 11568.89
Subtracting 585 from 600 leaves us 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.

Advancing to step 9:
If we divide 150 by 65, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 11568.892
Deduct 130 from 150 and we're left 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.

Moving on to step 10:
65 can be fit into 200 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 11568.8923
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.

On to step 11:
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: 11568.8923
The remainder is 50 after subtracting 0 from 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 12:
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: 11568.892307
The remainder is 45 after subtracting 455 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
The number 65 fits into 450 6 times, leaving a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 11568.8923076
If we subtract 390 from 450, we 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.

Moving on to step 14:
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: 11568.89230769
If we subtract 585 from 600, we 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.

The final result is 11568.89230769 with a remainder of 1.5e-08.
