We look at the division of 830311 by 65 
The aim is to understand the frequency of 65 in 830311.

On to step 1:
65 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 65

On to step 2:
65 can be fit into 83 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 18 after subtracting 65 from 83.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 65

Step 3:
If we divide 180 by 65, we get 2 and a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 50 after subtracting 130 from 180.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 65

Let's proceed to step 4:
When dividing 503 by 65, we get 7 with a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 127.0
The remainder is 48 after subtracting 455 from 503.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 65

On to step 5:
65 can be fit into 481 7 times, resulting in a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 1277.0
Subtract 455 from 481 to get 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 65

Let's proceed to step 6:
The number 65 fits into 261 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 12774.0
Subtracting 260 from 261 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
65 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12774.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
65 can be fit into 100 1 times, resulting in a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 12774.01
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.

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: 12774.015
If we take 325 away from 350, we end up 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.

Advancing to step 10:
65 goes into 250 3 times with a remainder of 55.
The next digit of our result is 3. 
Result so far: 12774.0153
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.

Moving on to step 11:
65 can be fit into 550 8 times, resulting in a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 12774.01538
Subtracting 520 from 550 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
300 divided by 65 is 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 12774.015384
If we take 260 away from 300, we end up with 40.
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 goes into 400 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 12774.0153846
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 65, we get 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 12774.01538461
If we take 65 away from 100, we end up 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.

In conclusion, the division gives 12774.01538461 with a balance of 3.5e-08.
