We're dividing 313115 by 66 
The aim is to understand the frequency of 66 in 313115.

Advancing to step 1:
3 divided by 66 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 66

Going ahead to step 2:
31 divided by 66 is 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 66

Step 3:
If we divide 313 by 66, we get 4 and a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 264 from 313 leaves us with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 66

Let's proceed to step 4:
When dividing 491 by 66, we get 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we subtract 462 from 491, we get 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 66

On to step 5:
If we divide 291 by 66, we get 4 and a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
The remainder is 27 after subtracting 264 from 291.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 66

Step 6:
275 divided by 66 is 4 with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4744.0
Subtracting 264 from 275 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
When dividing 110 by 66, we get 1 with a remainder of 44.
The next digit of our result is 1. 
Result so far: 4744.1
The remainder is 44 after subtracting 66 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
If we divide 440 by 66, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 4744.16
Subtract 396 from 440 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
66 can be fit into 440 6 times, resulting in a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 4744.166
Subtracting 396 from 440 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 4744.166 with a remainder of 0.0044.
