587278 divided by 66 
The aim is to understand the frequency of 66 in 587278.

Moving on to step 1:
66 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 66

Going ahead to step 2:
58 divided by 66 is 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Append the next digit (7) from the dividend to 58 and continue with: 587 / 66

Step 3:
When dividing 587 by 66, we get 8 with a remainder of 59.
The next digit of our result is 8. 
Result so far: 8.0
If we take 528 away from 587, we end up with 59.
Append the next digit (2) from the dividend to 59 and continue with: 592 / 66

Moving on to step 4:
592 divided by 66 is 8 with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
The remainder is 64 after subtracting 528 from 592.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 66

Going ahead to step 5:
647 divided by 66 is 9 with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 889.0
If we subtract 594 from 647, we get 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 66

Advancing to step 6:
66 goes into 538 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 8898.0
Subtracting 528 from 538 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 66 fits into 100 1 times, leaving a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 8898.1
If we subtract 66 from 100, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
66 can be fit into 340 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 8898.15
If we take 330 away from 340, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
The number 66 fits into 100 1 times, leaving a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 8898.151
Subtract 66 from 100 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
340 divided by 66 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 8898.1515
If we take 330 away from 340, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
When dividing 100 by 66, we get 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 8898.15151
The remainder is 34 after subtracting 66 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
340 divided by 66 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 8898.151515
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
The number 66 fits into 100 1 times, leaving a remainder of 34.
The next digit of our result is 1. 
Result so far: 8898.1515151
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
340 divided by 66 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 8898.15151515
Subtracting 330 from 340 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 8898.15151515 with a balance of 1e-08.
