Let's divide 575523 by 66
The aim is to understand the frequency of 66 in 575523.

Let's proceed 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
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 66

On to step 2:
The number 66 fits into 57 0 times, leaving a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 66

Going ahead to step 3:
The number 66 fits into 575 8 times, leaving a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 528 from 575 leaves us with 47.
Fetch the next digit (5) from the dividend, attach it to 47 and continue: 475 / 66

Advancing to step 4:
If we divide 475 by 66, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we take 462 away from 475, we end up with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 66

Step 5:
If we divide 132 by 66, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 872.0
If we take 132 away from 132, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 66

Moving on to step 6:
The number 66 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 8720.0
Deduct 0 from 3 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 66 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 8720.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
If we divide 300 by 66, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 8720.04
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8720.045
Subtracting 330 from 360 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
66 goes into 300 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 8720.0454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 8720.04545
Subtracting 330 from 360 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 8720.045454
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
When dividing 360 by 66, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 8720.0454545
Subtracting 330 from 360 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
300 divided by 66 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 8720.04545454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 8720.04545454 with a balance of 3.6e-08.
