We look at the division of 3341717 by 855 
The aim is to understand the frequency of 855 in 3341717.

Step 1:
3 divided by 855 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 855

Advancing to step 2:
The number 855 fits into 33 0 times, leaving a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 855

Going ahead to step 3:
The number 855 fits into 334 0 times, leaving a remainder of 334.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 334, we end up with 334.
Fetch the next digit (1) from the dividend, attach it to 334 and continue: 3341 / 855

Advancing to step 4:
3341 divided by 855 is 3 with a remainder of 776.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2565 from 3341 to get 776.
Bring next digit (7) of the dividend behind the 776 and repeat the process: 7767 / 855

Let's proceed to step 5:
7767 divided by 855 is 9 with a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 72 after subtracting 7695 from 7767.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 855

Let's proceed to step 6:
855 can be fit into 721 0 times, resulting in a remainder of 721.
Put 0 as the next digit of the answer. 
Result so far: 390.0
Subtract 0 from 721 to get 721.
Include the next digit (7) from the dividend after 721, then repeat: 7217 / 855

Going ahead to step 7:
If we divide 7217 by 855, we get 8 and a remainder of 377.
Record the quotient 8 as the next digit in the result. 
Result so far: 3908.0
Subtract 6840 from 7217 to get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Let's proceed to step 8:
The number 855 fits into 3770 4 times, leaving a remainder of 350.
Use 4 as the next digit of our solution. 
Result so far: 3908.4
If we take 3420 away from 3770, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 9:
If we divide 3500 by 855, we get 4 and a remainder of 80.
The next digit of our result is 4. 
Result so far: 3908.44
The remainder is 80 after subtracting 3420 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 3908.44, and the remainder is 0.08.
