We're dividing 635796 by 66 
The aim is to understand the frequency of 66 in 635796.

Step 1:
66 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 66

Going ahead to step 2:
If we divide 63 by 66, we get 0 and a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Fetch the next digit (5) from the dividend, attach it to 63 and continue: 635 / 66

Moving on to step 3:
66 goes into 635 9 times with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 594 from 635 leaves us with 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 66

Going ahead to step 4:
The number 66 fits into 417 6 times, leaving a remainder of 21.
The next digit of our result is 6. 
Result so far: 96.0
Deduct 396 from 417 and we're left with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 66

Going ahead to step 5:
The number 66 fits into 219 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 963.0
If we subtract 198 from 219, we get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 66

On to step 6:
216 divided by 66 is 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 9633.0
Subtract 198 from 216 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
180 divided by 66 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 9633.2
Subtract 132 from 180 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
If we divide 480 by 66, we get 7 and a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 9633.27
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
66 can be fit into 180 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 9633.272
Deduct 132 from 180 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
480 divided by 66 is 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 9633.2727
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
66 can be fit into 180 2 times, resulting in a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 9633.27272
If we take 132 away from 180, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
66 can be fit into 480 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 9633.272727
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
If we divide 180 by 66, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 9633.2727272
If we take 132 away from 180, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
66 goes into 480 7 times with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 9633.27272727
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 9633.27272727 and a remainder of 1.8e-08.
