23130 divided by 66 
The aim is to understand the frequency of 66 in 23130.

Moving on to step 1:
66 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 66

Step 2:
23 divided by 66 is 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 66

Step 3:
If we divide 231 by 66, we get 3 and a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 198 from 231 to get 33.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 66

Let's proceed to step 4:
66 can be fit into 333 5 times, resulting in a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 330 from 333 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 66

Advancing to step 5:
The number 66 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 350.0
Subtracting 0 from 30 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.

Let's proceed to step 6:
66 goes into 300 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 350.4
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.

Going ahead to step 7:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 350.45
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.

Let's proceed to step 8:
When dividing 300 by 66, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 350.454
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.

Going ahead to step 9:
When dividing 360 by 66, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 350.4545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
66 goes into 300 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 350.45454
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.

On to step 11:
360 divided by 66 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 350.454545
The remainder is 30 after subtracting 330 from 360.
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 12:
66 goes into 300 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 350.4545454
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.

Step 13:
If we divide 360 by 66, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 350.45454545
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.

The quotient of the division is 350.45454545, and the remainder is 3e-08.
