13852105 divided by 323 
We want to figure out the number of times 13852105 can be divided by 323.

Moving on to step 1:
1 divided by 323 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 323

On to step 2:
If we divide 13 by 323, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 323

On to step 3:
323 can be fit into 138 0 times, resulting in a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 138 after subtracting 0 from 138.
Fetch the next digit (5) from the dividend, attach it to 138 and continue: 1385 / 323

Step 4:
The number 323 fits into 1385 4 times, leaving a remainder of 93.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1292 from 1385 and we're left with 93.
Append the next digit (2) from the dividend to 93 and continue with: 932 / 323

Advancing to step 5:
The number 323 fits into 932 2 times, leaving a remainder of 286.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we take 646 away from 932, we end up with 286.
Take the next digit (1) from the dividend and append it to 286, then repeat: 2861 / 323

Let's proceed to step 6:
323 can be fit into 2861 8 times, resulting in a remainder of 277.
Put 8 as the next digit of the answer. 
Result so far: 428.0
Deduct 2584 from 2861 and we're left with 277.
Bring next digit (0) of the dividend behind the 277 and repeat the process: 2770 / 323

Moving on to step 7:
323 goes into 2770 8 times with a remainder of 186.
Record the quotient 8 as the next digit in the result. 
Result so far: 4288.0
If we take 2584 away from 2770, we end up with 186.
Bring next digit (5) of the dividend behind the 186 and repeat the process: 1865 / 323

Step 8:
The number 323 fits into 1865 5 times, leaving a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 42885.0
If we take 1615 away from 1865, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 9:
The number 323 fits into 2500 7 times, leaving a remainder of 239.
Use 7 as the next digit of our solution. 
Result so far: 42885.7
The remainder is 239 after subtracting 2261 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 10:
The number 323 fits into 2390 7 times, leaving a remainder of 129.
Record the quotient 7 as the next digit in the result. 
Result so far: 42885.77
Subtracting 2261 from 2390 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The final result is 42885.77 with a remainder of 0.129.
