502633 divided by 66 
The aim is to understand the frequency of 66 in 502633.

Going ahead to step 1:
66 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 66

Moving on to step 2:
If we divide 50 by 66, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Take the next digit (2) from the dividend and append it to 50, then repeat: 502 / 66

Advancing to step 3:
When dividing 502 by 66, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 462 from 502 to get 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 66

Going ahead to step 4:
If we divide 406 by 66, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 396 from 406 to get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 66

Advancing to step 5:
66 can be fit into 103 1 times, resulting in a remainder of 37.
The next digit of our result is 1. 
Result so far: 761.0
Subtracting 66 from 103 leaves us with 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 66

Moving on to step 6:
When dividing 373 by 66, we get 5 with a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 7615.0
Subtracting 330 from 373 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
The number 66 fits into 430 6 times, leaving a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 7615.6
If we take 396 away from 430, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
66 goes into 340 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 7615.65
Deduct 330 from 340 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
66 goes into 100 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 7615.651
Deduct 66 from 100 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
When dividing 340 by 66, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7615.6515
Subtracting 330 from 340 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
100 divided by 66 is 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 7615.65151
Deduct 66 from 100 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
66 goes into 340 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 7615.651515
Deduct 330 from 340 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
The number 66 fits into 100 1 times, leaving a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 7615.6515151
Subtract 66 from 100 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
66 can be fit into 340 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 7615.65151515
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 7615.65151515 with a remainder of 1e-08.
