We divide 13153166 by 855
The aim is to understand the frequency of 855 in 13153166.

Advancing to step 1:
855 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 855

Going ahead to step 2:
The number 855 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 855

Advancing to step 3:
The number 855 fits into 131 0 times, leaving a remainder of 131.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 131 leaves us with 131.
Grab the next digit (5) from the dividend, add it to 131, then carry on: 1315 / 855

Advancing to step 4:
If we divide 1315 by 855, we get 1 and a remainder of 460.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 855 from 1315, we get 460.
Bring next digit (3) of the dividend behind the 460 and repeat the process: 4603 / 855

On to step 5:
855 goes into 4603 5 times with a remainder of 328.
The next digit of our result is 5. 
Result so far: 15.0
If we take 4275 away from 4603, we end up with 328.
Include the next digit (1) from the dividend after 328, then repeat: 3281 / 855

On to step 6:
The number 855 fits into 3281 3 times, leaving a remainder of 716.
Use 3 as the next digit of our solution. 
Result so far: 153.0
The remainder is 716 after subtracting 2565 from 3281.
Take the next digit (6) from the dividend and append it to 716, then repeat: 7166 / 855

Moving on to step 7:
855 goes into 7166 8 times with a remainder of 326.
Use 8 as the next digit of our solution. 
Result so far: 1538.0
Subtracting 6840 from 7166 leaves us with 326.
Include the next digit (6) from the dividend after 326, then repeat: 3266 / 855

Moving on to step 8:
855 can be fit into 3266 3 times, resulting in a remainder of 701.
The next digit of our result is 3. 
Result so far: 15383.0
If we take 2565 away from 3266, we end up with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Advancing to step 9:
If we divide 7010 by 855, we get 8 and a remainder of 170.
The number 8 becomes the next digit in our result. 
Result so far: 15383.8
Subtract 6840 from 7010 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 10:
855 can be fit into 1700 1 times, resulting in a remainder of 845.
The number 1 becomes the next digit in our result. 
Result so far: 15383.81
The remainder is 845 after subtracting 855 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Going ahead to step 11:
855 can be fit into 8450 9 times, resulting in a remainder of 755.
Record the quotient 9 as the next digit in the result. 
Result so far: 15383.819
Subtracting 7695 from 8450 leaves us with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

On to step 12:
855 goes into 7550 8 times with a remainder of 710.
Record the quotient 8 as the next digit in the result. 
Result so far: 15383.8198
If we take 6840 away from 7550, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Moving on to step 13:
855 can be fit into 7100 8 times, resulting in a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 15383.81988
Deduct 6840 from 7100 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final result is 15383.81988 with a remainder of 0.00026.
