496966 divided by 66 
The aim is to understand the frequency of 66 in 496966.

On to step 1:
The number 66 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 66

Going ahead to step 2:
66 goes into 49 0 times with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Append the next digit (6) from the dividend to 49 and continue with: 496 / 66

Let's proceed to step 3:
If we divide 496 by 66, we get 7 and a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 462 from 496, we get 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 66

Going ahead to step 4:
349 divided by 66 is 5 with a remainder of 19.
The next digit of our result is 5. 
Result so far: 75.0
Deduct 330 from 349 and we're left with 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 66

Step 5:
When dividing 196 by 66, we get 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 752.0
Subtracting 132 from 196 leaves us with 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 66

Advancing to step 6:
646 divided by 66 is 9 with a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 7529.0
If we take 594 away from 646, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 7:
If we divide 520 by 66, we get 7 and a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 7529.7
Deduct 462 from 520 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 8:
The number 66 fits into 580 8 times, leaving a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 7529.78
Subtract 528 from 580 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 9:
If we divide 520 by 66, we get 7 and a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 7529.787
If we subtract 462 from 520, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
When dividing 580 by 66, we get 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 7529.7878
If we take 528 away from 580, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
520 divided by 66 is 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 7529.78787
Deduct 462 from 520 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
When dividing 580 by 66, we get 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 7529.787878
Deduct 528 from 580 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
520 divided by 66 is 7 with a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 7529.7878787
If we take 462 away from 520, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 14:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 7529.78787878
Subtract 528 from 580 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.

The final result is 7529.78787878 with a remainder of 5.2e-08.
