Let's divide 452557 by 66
The aim is to understand the frequency of 66 in 452557.

Let's proceed to step 1:
The number 66 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 66

Let's proceed to step 2:
The number 66 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 66

Going ahead to step 3:
66 goes into 452 6 times with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 56 after subtracting 396 from 452.
Grab the next digit (5) from the dividend, add it to 56, then carry on: 565 / 66

Let's proceed to step 4:
66 goes into 565 8 times with a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 68.0
The remainder is 37 after subtracting 528 from 565.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 66

Moving on to step 5:
66 goes into 375 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 685.0
Deduct 330 from 375 and we're left with 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 66

On to step 6:
When dividing 457 by 66, we get 6 with a remainder of 61.
Record the quotient 6 as the next digit in the result. 
Result so far: 6856.0
The remainder is 61 after subtracting 396 from 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 7:
610 divided by 66 is 9 with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 6856.9
If we take 594 away from 610, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
The number 66 fits into 160 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 6856.92
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
The number 66 fits into 280 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 6856.924
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
160 divided by 66 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 6856.9242
Subtracting 132 from 160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
The number 66 fits into 280 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 6856.92424
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
66 can be fit into 160 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 6856.924242
Subtracting 132 from 160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
The number 66 fits into 280 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 6856.9242424
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
66 goes into 160 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 6856.92424242
Deduct 132 from 160 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 6856.92424242 and a remainder of 2.8e-08.
