We look at the division of 593922 by 66 
The aim is to understand the frequency of 66 in 593922.

Moving on to step 1:
If we divide 5 by 66, we get 0 and 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.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 66

On to step 2:
When dividing 59 by 66, we get 0 with a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 59 leaves us with 59.
Include the next digit (3) from the dividend after 59, then repeat: 593 / 66

Step 3:
If we divide 593 by 66, we get 8 and a remainder of 65.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 528 from 593, we get 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 66

Let's proceed to step 4:
66 goes into 659 9 times with a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
The remainder is 65 after subtracting 594 from 659.
Take the next digit (2) from the dividend and append it to 65, then repeat: 652 / 66

Going ahead to step 5:
The number 66 fits into 652 9 times, leaving a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 899.0
Deduct 594 from 652 and we're left with 58.
Fetch the next digit (2) from the dividend, attach it to 58 and continue: 582 / 66

Going ahead to step 6:
If we divide 582 by 66, we get 8 and a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 8998.0
The remainder is 54 after subtracting 528 from 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8998.8
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
The number 66 fits into 120 1 times, leaving a remainder of 54.
The next digit of our result is 1. 
Result so far: 8998.81
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
66 goes into 540 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8998.818
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
When dividing 120 by 66, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 8998.8181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
If we divide 540 by 66, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8998.81818
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
If we divide 120 by 66, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 8998.818181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
If we divide 540 by 66, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8998.8181818
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
If we divide 120 by 66, we get 1 and a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 8998.81818181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 8998.81818181 with a balance of 5.4e-08.
