We divide 539707 by 66
The aim is to understand the frequency of 66 in 539707.

Let's proceed to step 1:
66 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 66

On to step 2:
66 can be fit into 53 0 times, resulting in a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 66

Step 3:
The number 66 fits into 539 8 times, leaving a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 528 from 539 leaves us with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 66

Let's proceed to step 4:
If we divide 117 by 66, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 51 after subtracting 66 from 117.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 66

Let's proceed to step 5:
66 goes into 510 7 times with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 817.0
Subtracting 462 from 510 leaves us with 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 66

Step 6:
If we divide 487 by 66, we get 7 and a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 8177.0
If we take 462 away from 487, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
When dividing 250 by 66, we get 3 with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 8177.3
Subtract 198 from 250 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.

Step 8:
66 goes into 520 7 times with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 8177.37
Subtracting 462 from 520 leaves us 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.

Going ahead to step 9:
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: 8177.378
The remainder is 52 after subtracting 528 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
66 can be fit into 520 7 times, resulting in a remainder of 58.
The next digit of our result is 7. 
Result so far: 8177.3787
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.

On to step 11:
580 divided by 66 is 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 8177.37878
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.

Step 12:
66 can be fit into 520 7 times, resulting in a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 8177.378787
Subtract 462 from 520 to 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.

Going ahead to step 13:
66 can be fit into 580 8 times, resulting in a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 8177.3787878
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.

Moving on to step 14:
The number 66 fits into 520 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 8177.37878787
Subtracting 462 from 520 leaves us 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.

The final result is 8177.37878787 with a remainder of 5.8e-08.
