We look at the division of 656973 by 65 
The aim is to understand the frequency of 65 in 656973.

On to step 1:
When dividing 6 by 65, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 65

Let's proceed to step 2:
The number 65 fits into 65 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 65 from 65 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 65

Moving on to step 3:
65 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 65

Going ahead to step 4:
When dividing 69 by 65, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we take 65 away from 69, we end up with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 65

Let's proceed to step 5:
When dividing 47 by 65, we get 0 with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 1010.0
Deduct 0 from 47 and we're left with 47.
Grab the next digit (3) from the dividend, add it to 47, then carry on: 473 / 65

Advancing to step 6:
The number 65 fits into 473 7 times, leaving a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 10107.0
Deduct 455 from 473 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
When dividing 180 by 65, we get 2 with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 10107.2
The remainder is 50 after subtracting 130 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
The number 65 fits into 500 7 times, leaving a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 10107.27
If we subtract 455 from 500, we get 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 9:
65 can be fit into 450 6 times, resulting in a remainder of 60.
The next digit of our result is 6. 
Result so far: 10107.276
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.

Step 10:
65 goes into 600 9 times with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 10107.2769
The remainder is 15 after subtracting 585 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
150 divided by 65 is 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 10107.27692
Subtract 130 from 150 to get 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 12:
If we divide 200 by 65, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 10107.276923
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.

Let's proceed to step 13:
When dividing 50 by 65, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10107.276923
If we subtract 0 from 50, we 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.

Going ahead to step 14:
500 divided by 65 is 7 with a remainder of 45.
The next digit of our result is 7. 
Result so far: 10107.27692307
If we subtract 455 from 500, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 10107.27692307, with a leftover of 4.5e-08.
