We're dividing 287859 by 13 
The aim is to understand the frequency of 13 in 287859.

Moving on to step 1:
2 divided by 13 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 13

Going ahead to step 2:
28 divided by 13 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 26 away from 28, we end up with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 13

Let's proceed to step 3:
When dividing 27 by 13, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 1 after subtracting 26 from 27.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 13

Let's proceed to step 4:
When dividing 18 by 13, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 221.0
Deduct 13 from 18 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 13

Moving on to step 5:
13 can be fit into 55 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 2214.0
Deduct 52 from 55 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 13

Going ahead to step 6:
When dividing 39 by 13, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 22143.0
If we take 39 away from 39, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
13 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22143.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 13, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22143.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 22143.0 with a balance of 0.0.
