219709 divided by 66 
The aim is to understand the frequency of 66 in 219709.

On to step 1:
66 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 66

Going ahead to step 2:
When dividing 21 by 66, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 66

On to step 3:
66 goes into 219 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 198 away from 219, we end up with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 66

Step 4:
If we divide 217 by 66, we get 3 and a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 198 from 217, we get 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 66

Let's proceed to step 5:
190 divided by 66 is 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 332.0
Deduct 132 from 190 and we're left with 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 66

Going ahead to step 6:
When dividing 589 by 66, we get 8 with a remainder of 61.
Record the quotient 8 as the next digit in the result. 
Result so far: 3328.0
Subtract 528 from 589 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
66 goes into 610 9 times with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 3328.9
The remainder is 16 after subtracting 594 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
When dividing 160 by 66, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 3328.92
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.

On to step 9:
280 divided by 66 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 3328.924
Subtracting 264 from 280 leaves us 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.

Moving on to step 10:
160 divided by 66 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 3328.9242
If we take 132 away from 160, we end up 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 11:
280 divided by 66 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 3328.92424
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.

Let's proceed to step 12:
When dividing 160 by 66, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 3328.924242
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.

Going ahead to step 13:
66 goes into 280 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 3328.9242424
If we subtract 264 from 280, we 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.

Moving on to step 14:
When dividing 160 by 66, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 3328.92424242
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.

The final result is 3328.92424242 with a remainder of 2.8e-08.
