We divide 660777 by 65
The aim is to understand the frequency of 65 in 660777.

Advancing to step 1:
6 divided by 65 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 65

Moving on to step 2:
If we divide 66 by 65, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 65 from 66, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 65

Step 3:
When dividing 10 by 65, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 65

On to step 4:
65 can be fit into 107 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtract 65 from 107 to get 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 65

Advancing to step 5:
427 divided by 65 is 6 with a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 1016.0
If we subtract 390 from 427, we get 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 65

Let's proceed to step 6:
65 can be fit into 377 5 times, resulting in a remainder of 52.
Write down 5 as next digit of the result. 
Result so far: 10165.0
Subtract 325 from 377 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
520 divided by 65 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 10165.8
Subtracting 520 from 520 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 65, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10165.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 65, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10165.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 10165.8 with a remaining 0.0.
