We divide 65077693 by 666
The aim is to understand the frequency of 666 in 65077693.

Going ahead to step 1:
When dividing 6 by 666, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 666

Let's proceed to step 2:
The number 666 fits into 65 0 times, leaving a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 666

Step 3:
650 divided by 666 is 0 with a remainder of 650.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 650 and we're left with 650.
Grab the next digit (7) from the dividend, add it to 650, then carry on: 6507 / 666

On to step 4:
When dividing 6507 by 666, we get 9 with a remainder of 513.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 5994 from 6507, we get 513.
Bring next digit (7) of the dividend behind the 513 and repeat the process: 5137 / 666

On to step 5:
666 can be fit into 5137 7 times, resulting in a remainder of 475.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we subtract 4662 from 5137, we get 475.
Include the next digit (6) from the dividend after 475, then repeat: 4756 / 666

Moving on to step 6:
If we divide 4756 by 666, we get 7 and a remainder of 94.
Record the quotient 7 as the next digit in the result. 
Result so far: 977.0
Subtracting 4662 from 4756 leaves us with 94.
Include the next digit (9) from the dividend after 94, then repeat: 949 / 666

Moving on to step 7:
The number 666 fits into 949 1 times, leaving a remainder of 283.
Write down 1 as next digit of the result. 
Result so far: 9771.0
The remainder is 283 after subtracting 666 from 949.
Grab the next digit (3) from the dividend, add it to 283, then carry on: 2833 / 666

Going ahead to step 8:
The number 666 fits into 2833 4 times, leaving a remainder of 169.
The number 4 becomes the next digit in our result. 
Result so far: 97714.0
Deduct 2664 from 2833 and we're left with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 9:
666 goes into 1690 2 times with a remainder of 358.
The next digit of our result is 2. 
Result so far: 97714.2
Subtract 1332 from 1690 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 10:
The number 666 fits into 3580 5 times, leaving a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 97714.25
If we subtract 3330 from 3580, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 11:
If we divide 2500 by 666, we get 3 and a remainder of 502.
The next digit of our result is 3. 
Result so far: 97714.253
Subtracting 1998 from 2500 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Moving on to step 12:
When dividing 5020 by 666, we get 7 with a remainder of 358.
Record the quotient 7 as the next digit in the result. 
Result so far: 97714.2537
If we subtract 4662 from 5020, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 13:
666 goes into 3580 5 times with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 97714.25375
Subtract 3330 from 3580 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 14:
If we divide 2500 by 666, we get 3 and a remainder of 502.
Use 3 as the next digit of our solution. 
Result so far: 97714.253753
Subtracting 1998 from 2500 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Let's proceed to step 15:
666 goes into 5020 7 times with a remainder of 358.
The number 7 becomes the next digit in our result. 
Result so far: 97714.2537537
Subtract 4662 from 5020 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 16:
666 goes into 3580 5 times with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 97714.25375375
If we subtract 3330 from 3580, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Our division results in 97714.25375375 with a remaining 2.5e-07.
