13263299 divided by 389 
The aim is to understand the frequency of 389 in 13263299.

On to step 1:
389 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
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 / 389

Moving on to step 2:
389 can be fit into 13 0 times, resulting in a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 389

Let's proceed to step 3:
389 goes into 132 0 times with a remainder of 132.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 132, we end up with 132.
Take the next digit (6) from the dividend and append it to 132, then repeat: 1326 / 389

Moving on to step 4:
The number 389 fits into 1326 3 times, leaving a remainder of 159.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1167 from 1326 and we're left with 159.
Take the next digit (3) from the dividend and append it to 159, then repeat: 1593 / 389

Let's proceed to step 5:
If we divide 1593 by 389, we get 4 and a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 34.0
The remainder is 37 after subtracting 1556 from 1593.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 389

On to step 6:
372 divided by 389 is 0 with a remainder of 372.
The next digit of our result is 0. 
Result so far: 340.0
If we subtract 0 from 372, we get 372.
Fetch the next digit (9) from the dividend, attach it to 372 and continue: 3729 / 389

Going ahead to step 7:
If we divide 3729 by 389, we get 9 and a remainder of 228.
Put 9 as the next digit of the answer. 
Result so far: 3409.0
The remainder is 228 after subtracting 3501 from 3729.
Include the next digit (9) from the dividend after 228, then repeat: 2289 / 389

Step 8:
If we divide 2289 by 389, we get 5 and a remainder of 344.
Write down 5 as next digit of the result. 
Result so far: 34095.0
If we take 1945 away from 2289, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 9:
The number 389 fits into 3440 8 times, leaving a remainder of 328.
The next digit of our result is 8. 
Result so far: 34095.8
Subtracting 3112 from 3440 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 10:
389 goes into 3280 8 times with a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 34095.88
If we take 3112 away from 3280, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

After the division, we end up with 34095.88 and a remainder of 0.168.
