We divide 647066 by 66
The aim is to understand the frequency of 66 in 647066.

Step 1:
If we divide 6 by 66, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 66

Moving on to step 2:
64 divided by 66 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (7) from the dividend after 64, then repeat: 647 / 66

Step 3:
647 divided by 66 is 9 with a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 53 after subtracting 594 from 647.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 66

Let's proceed to step 4:
530 divided by 66 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 98.0
Deduct 528 from 530 and we're left with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 66

Let's proceed to step 5:
The number 66 fits into 26 0 times, leaving a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 980.0
If we take 0 away from 26, we end up with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 66

Moving on to step 6:
66 can be fit into 266 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 9804.0
If we take 264 away from 266, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9804.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
When dividing 200 by 66, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 9804.03
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
66 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 9804.03
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
66 can be fit into 200 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 9804.0303
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9804.0303
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
The number 66 fits into 200 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 9804.030303
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
If we divide 20 by 66, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9804.030303
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
200 divided by 66 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 9804.03030303
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 9804.03030303 with a remainder of 2e-09.
