We divide 655510 by 66
The aim is to understand the frequency of 66 in 655510.

Advancing to step 1:
The number 66 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 66

Advancing to step 2:
The number 66 fits into 65 0 times, leaving a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Fetch the next digit (5) from the dividend, attach it to 65 and continue: 655 / 66

Step 3:
66 can be fit into 655 9 times, resulting in a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 594 from 655 and we're left with 61.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 66

Let's proceed to step 4:
615 divided by 66 is 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we subtract 594 from 615, we get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 66

Going ahead to step 5:
66 goes into 211 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 993.0
If we take 198 away from 211, we end up with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 66

On to step 6:
When dividing 130 by 66, we get 1 with a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 9931.0
Subtract 66 from 130 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 7:
640 divided by 66 is 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 9931.9
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
66 goes into 460 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 9931.96
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
66 goes into 640 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 9931.969
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
460 divided by 66 is 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 9931.9696
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
66 goes into 640 9 times with a remainder of 46.
The next digit of our result is 9. 
Result so far: 9931.96969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
66 can be fit into 460 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 9931.969696
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
When dividing 640 by 66, we get 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 9931.9696969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
66 goes into 460 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 9931.96969696
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 9931.96969696, and the remainder is 6.4e-08.
