We look at the division of 664662 by 65 
The aim is to understand the frequency of 65 in 664662.

Moving on to step 1:
If we divide 6 by 65, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 65

Going ahead to step 2:
If we divide 66 by 65, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 65 from 66 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 65

Step 3:
65 goes into 14 0 times with a remainder of 14.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 14 after subtracting 0 from 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 65

Step 4:
65 can be fit into 146 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 102.0
The remainder is 16 after subtracting 130 from 146.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 65

On to step 5:
The number 65 fits into 166 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 1022.0
Deduct 130 from 166 and we're left with 36.
Grab the next digit (2) from the dividend, add it to 36, then carry on: 362 / 65

Let's proceed to step 6:
65 goes into 362 5 times with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 10225.0
Subtract 325 from 362 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
370 divided by 65 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 10225.5
Deduct 325 from 370 and we're left 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.

Moving on to step 8:
450 divided by 65 is 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 10225.56
If we take 390 away from 450, 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 9:
If we divide 600 by 65, we get 9 and a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 10225.569
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.

Let's proceed to step 10:
150 divided by 65 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 10225.5692
If we take 130 away from 150, we end up 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.

On to step 11:
65 can be fit into 200 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 10225.56923
Subtracting 195 from 200 leaves us 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.

Step 12:
65 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 10225.56923
Subtract 0 from 50 to get 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 13:
When dividing 500 by 65, we get 7 with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 10225.5692307
If we take 455 away from 500, we end up 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.

On to step 14:
The number 65 fits into 450 6 times, leaving a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 10225.56923076
Deduct 390 from 450 and we're left 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.

In conclusion, the division gives 10225.56923076 with a balance of 6e-08.
