Let's divide 965908 by 66
The aim is to understand the frequency of 66 in 965908.

On to step 1:
When dividing 9 by 66, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 66

Going ahead to step 2:
66 can be fit into 96 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 30 after subtracting 66 from 96.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 66

Advancing to step 3:
66 goes into 305 4 times with a remainder of 41.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 264 from 305 leaves us with 41.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 66

Let's proceed to step 4:
419 divided by 66 is 6 with a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 146.0
If we take 396 away from 419, we end up with 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 66

Going ahead to step 5:
If we divide 230 by 66, we get 3 and a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 1463.0
Deduct 198 from 230 and we're left with 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 66

On to step 6:
66 goes into 328 4 times with a remainder of 64.
The next digit of our result is 4. 
Result so far: 14634.0
If we subtract 264 from 328, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
If we divide 640 by 66, we get 9 and a remainder of 46.
The next digit of our result is 9. 
Result so far: 14634.9
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 14634.96
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 14634.969
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 14634.9696
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
If we divide 640 by 66, we get 9 and a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 14634.96969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
66 goes into 460 6 times with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 14634.969696
Subtracting 396 from 460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
66 goes into 640 9 times with a remainder of 46.
The next digit of our result is 9. 
Result so far: 14634.9696969
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
66 goes into 460 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 14634.96969696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 14634.96969696 with a remainder of 6.4e-08.
