We're dividing 321920 by 65 
The aim is to understand the frequency of 65 in 321920.

Let's proceed to step 1:
65 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 65

Moving on to step 2:
If we divide 32 by 65, we get 0 and a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 65

Going ahead to step 3:
321 divided by 65 is 4 with a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 260 from 321 leaves us with 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 65

Step 4:
619 divided by 65 is 9 with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Deduct 585 from 619 and we're left with 34.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 65

Let's proceed to step 5:
342 divided by 65 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 495.0
The remainder is 17 after subtracting 325 from 342.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 65

Advancing to step 6:
When dividing 170 by 65, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 4952.0
If we subtract 130 from 170, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
400 divided by 65 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 4952.6
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 65, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 4952.61
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.

Advancing to step 9:
350 divided by 65 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 4952.615
The remainder is 25 after subtracting 325 from 350.
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:
If we divide 250 by 65, we get 3 and a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 4952.6153
If we subtract 195 from 250, we 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.

On to step 11:
If we divide 550 by 65, we get 8 and a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 4952.61538
If we subtract 520 from 550, we get 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.
Write down 4 as next digit of the result. 
Result so far: 4952.615384
Subtract 260 from 300 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
400 divided by 65 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 4952.6153846
If we take 390 away from 400, we end up 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.

Moving on to step 14:
When dividing 100 by 65, we get 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 4952.61538461
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.

In conclusion, the division gives 4952.61538461 with a balance of 3.5e-08.
