We're dividing 567537 by 66 
The aim is to understand the frequency of 66 in 567537.

Moving on to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 66

On to step 2:
66 can be fit into 56 0 times, resulting in a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Include the next digit (7) from the dividend after 56, then repeat: 567 / 66

On to step 3:
567 divided by 66 is 8 with a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 39 after subtracting 528 from 567.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 66

Going ahead to step 4:
395 divided by 66 is 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 65 after subtracting 330 from 395.
Take the next digit (3) from the dividend and append it to 65, then repeat: 653 / 66

Going ahead to step 5:
66 goes into 653 9 times with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 859.0
If we take 594 away from 653, we end up with 59.
Grab the next digit (7) from the dividend, add it to 59, then carry on: 597 / 66

Let's proceed to step 6:
The number 66 fits into 597 9 times, leaving a remainder of 3.
The next digit of our result is 9. 
Result so far: 8599.0
Subtract 594 from 597 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
66 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 8599.0
If we subtract 0 from 30, we 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.

Going ahead to step 8:
66 can be fit into 300 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 8599.04
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.

Moving on to step 9:
When dividing 360 by 66, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 8599.045
If we subtract 330 from 360, we 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.

Going ahead to step 10:
When dividing 300 by 66, we get 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 8599.0454
If we take 264 away from 300, we end up 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:
If we divide 360 by 66, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 8599.04545
If we take 330 away from 360, we end up 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:
300 divided by 66 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 8599.045454
Deduct 264 from 300 and we're left 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.

Moving on to step 13:
When dividing 360 by 66, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8599.0454545
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.

Step 14:
When dividing 300 by 66, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 8599.04545454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 8599.04545454, with a leftover of 3.6e-08.
