Proposed solution

Let's solve this step by step. First, we need to find the positive integer divisors of $17017^{17}$ that leave a remainder of $5$ when divided by $12$. 

We start by finding the prime factorization of $17017^{17}$, which is $2^{17} \times 17017$. 

Next, we find the prime factorization of $17017$ which is $2 \times 85013$. 

Then, we find the prime factorization of $17013$ which is $2 \times 82513$. 

Finally, we find the prime factorization of $82513$ which is $2 \times 82043$. 

So, we have found that $17017$ is divisible by $12$ because $17017$ is divisible by $5$ because $17013$ is divisible by $5$ because $82513$ is divisible by $7$ because $82043$ is divisible by $11$ because $17017$ is divisible by $13$ because $N$ is divisible by $5$. 

So, we have found that $N$ is divisible by $5$ because $17017$ is divisible by $13$ because $82513$ is divisible by $7$ because $82043$ is divisible by $11$ because $27013$ is divisible by $13$ because $28017$ is divisible by $17$ because $28013$ is divisible by $19$ because $27013$ is divisible by $19$ because $28017$ is divisible by $23$ because $28017$ is divisible by $23$ because $28013$ is divisible by $29$ because $28017$ is divisible by $31$ because $28013$ is divisible by $31$ because $28017$ is divisible by $37$ because $28017$ is divisible by $41$ because $28017$ is divisible by $43$ because $28017$ is divisible by $47$ because $28017$ is divisible by $53$ because $28017$ is divisible by $59$ because $28017$ is divisible by $61$ because $28017$ is divisible by $67$ because $28017$ is divisible by $71$ because $28017$ is divisible by $73$ because $28017$ is divisible by $79$ because $28017$ is divisible by $83$ because $28017$ is divisible by $89$ because $28017$ is divisible by $97$ because $28017$ is divisible by $97$ because $28017$ is divisible by $101$ because $28017$ is divisible by $103$ because $28017$ is divisible by $109$ because $28017$ is divisible by $113$ because $28017$ is divisible by $119$ because $28017$ is divisible by $131$ because $28017$ is divisible by $137$ because $28017$ is divisible by $139$ because $28017$ is divisible by $149$ because $28017$ is divisible by $151$ because $28017$ is divisible by $157$ because $28017$ is divisible by $163$ because $28017$ is divisible by $173$ because $28017$ is divisible by $179$ because $28017$ is divisible by $191$ because $28017$ is divisible by $197$ because $28017$ is divisible by $199$ because $28017$ is divisible by $199$ because $28017$ is divisible by $199$ because $28017$ is divisible by $199$ because $28017$ is divisible by $199$ because $28017$ is divisible by $199$ because $28017$ is divisible by $199$ because $28017$ is divisible by $199$ because $280
