We look at the division of 96521 by 65 
The aim is to understand the frequency of 65 in 96521.

Going ahead to step 1:
If we divide 9 by 65, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 65

Let's proceed to step 2:
96 divided by 65 is 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 31 after subtracting 65 from 96.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 65

Moving on to step 3:
If we divide 315 by 65, we get 4 and a remainder of 55.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 260 from 315 leaves us with 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 65

Let's proceed to step 4:
When dividing 552 by 65, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
Subtracting 520 from 552 leaves us with 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 65

On to step 5:
When dividing 321 by 65, we get 4 with a remainder of 61.
Record the quotient 4 as the next digit in the result. 
Result so far: 1484.0
If we subtract 260 from 321, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 6:
65 can be fit into 610 9 times, resulting in a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 1484.9
If we take 585 away from 610, 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.

Moving on to step 7:
65 can be fit into 250 3 times, resulting in a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 1484.93
Subtracting 195 from 250 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
550 divided by 65 is 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 1484.938
Deduct 520 from 550 and we're left 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.

Advancing to step 9:
When dividing 300 by 65, we get 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 1484.9384
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 10:
When dividing 400 by 65, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 1484.93846
Subtract 390 from 400 to get 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 11:
65 can be fit into 100 1 times, resulting in a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1484.938461
The remainder is 35 after subtracting 65 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
65 can be fit into 350 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1484.9384615
Subtracting 325 from 350 leaves us 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.

Moving on to step 13:
When dividing 250 by 65, we get 3 with a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 1484.93846153
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.

The final result is 1484.93846153 with a remainder of 5.5e-08.
