318391 divided by 66 
The aim is to understand the frequency of 66 in 318391.

Moving on to step 1:
When dividing 3 by 66, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 66

Let's proceed to step 2:
When dividing 31 by 66, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 66

Let's proceed to step 3:
When dividing 318 by 66, we get 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 264 from 318 and we're left with 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 66

Moving on to step 4:
543 divided by 66 is 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
The remainder is 15 after subtracting 528 from 543.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 66

Advancing to step 5:
66 can be fit into 159 2 times, resulting in a remainder of 27.
The next digit of our result is 2. 
Result so far: 482.0
If we take 132 away from 159, we end up with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 66

Moving on to step 6:
The number 66 fits into 271 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4824.0
Subtract 264 from 271 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 66, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 4824.1
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
66 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 4824.1
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
400 divided by 66 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 4824.106
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
The number 66 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 4824.106
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
400 divided by 66 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 4824.10606
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
The number 66 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4824.10606
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
66 can be fit into 400 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 4824.1060606
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
66 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4824.1060606
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 4824.1060606 with a balance of 4e-08.
