We look at the division of 887315 by 13 
The aim is to understand the frequency of 13 in 887315.

Advancing to step 1:
When dividing 8 by 13, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 13

Let's proceed to step 2:
13 can be fit into 88 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 78 away from 88, we end up with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 13

On to step 3:
When dividing 107 by 13, we get 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 68.0
Subtracting 104 from 107 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 13

Going ahead to step 4:
When dividing 33 by 13, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 682.0
Deduct 26 from 33 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 13

Let's proceed to step 5:
71 divided by 13 is 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 6825.0
If we take 65 away from 71, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 13

Step 6:
If we divide 65 by 13, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 68255.0
Subtracting 65 from 65 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.

Step 7:
13 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 68255.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
When dividing 0 by 13, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 68255.0
If we take 0 away from 0, 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.

Our division results in 68255.0 with a remaining 0.0.
