Let's divide 21326 by 66
The aim is to understand the frequency of 66 in 21326.

Moving on to step 1:
When dividing 2 by 66, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 66

Let's proceed to step 2:
66 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 66

Let's proceed to step 3:
66 can be fit into 213 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 15 after subtracting 198 from 213.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 66

Step 4:
When dividing 152 by 66, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 132 from 152, we get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 66

Going ahead to step 5:
66 can be fit into 206 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 323.0
If we subtract 198 from 206, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 6:
The number 66 fits into 80 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 323.1
If we take 66 away from 80, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
140 divided by 66 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 323.12
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
If we divide 80 by 66, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 323.121
If we take 66 away from 80, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
The number 66 fits into 140 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 323.1212
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
The number 66 fits into 80 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 323.12121
Subtract 66 from 80 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
If we divide 140 by 66, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 323.121212
If we take 132 away from 140, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
66 goes into 80 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 323.1212121
If we subtract 66 from 80, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
If we divide 140 by 66, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 323.12121212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 323.12121212 with a balance of 8e-09.
