Let's divide 830394 by 65
The aim is to understand the frequency of 65 in 830394.

Step 1:
65 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 65

Moving on to step 2:
65 goes into 83 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 65 from 83, we get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 65

Going ahead to step 3:
When dividing 180 by 65, we get 2 with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 130 from 180 leaves us with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 65

Moving on to step 4:
503 divided by 65 is 7 with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
Deduct 455 from 503 and we're left with 48.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 65

Moving on to step 5:
489 divided by 65 is 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 1277.0
If we subtract 455 from 489, we get 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 65

Step 6:
344 divided by 65 is 5 with a remainder of 19.
The next digit of our result is 5. 
Result so far: 12775.0
Subtract 325 from 344 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
When dividing 190 by 65, we get 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 12775.2
If we subtract 130 from 190, 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.

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: 12775.29
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.

Step 9:
If we divide 150 by 65, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 12775.292
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.

Let's proceed to step 10:
200 divided by 65 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 12775.2923
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.

Advancing to step 11:
If we divide 50 by 65, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 12775.2923
Subtracting 0 from 50 leaves us 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 12:
65 can be fit into 500 7 times, resulting in a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 12775.292307
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.

Step 13:
The number 65 fits into 450 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 12775.2923076
The remainder is 60 after subtracting 390 from 450.
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 14:
The number 65 fits into 600 9 times, leaving a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 12775.29230769
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.

After the division, we end up with 12775.29230769 and a remainder of 1.5e-08.
