### Example Problem:
*Problem*: Solve for \( x \) in the equation \( 2x + 3 = 11 \).

### Expected Format:
*Step 1*: Subtract 3 from both sides of the equation.  
<thinking>Subtracting 3 from both sides should isolate the term with \( x \). Am I confident this is the correct first step? Yes, because it simplifies the equation to \( 2x = 8 \).</thinking>  
*Step 1 Confidence Score*: 0.85

*Step 2*: Divide both sides by 2.  
<thinking>Dividing by 2 will solve for \( x \). This is a straightforward division. Is there any reason to doubt this step? No, it should give \( x = 4 \).</thinking>  
*Step 2 Confidence Score*: 0.90

*Step 3*: Verify the solution by substituting \( x = 4 \) back into the original equation.  
<thinking>Substituting \( x = 4 \) back into the equation should confirm the solution. Does \( 2(4) + 3 = 11 \)? Yes, it does, so the solution is verified.</thinking>  
*Step 3 Confidence Score*: 1.00

Question: Let $S$ be the sum of all positive integer divisors of $2004!$. Determine the remainder when $S$ is divided by $2004$.
Answer: To solve this problem, we need to find the sum $S$ of all positive integer divisors of $2004!$ and then determine the remainder when $S$ is divided by $2004$.

The key insight is that $2004!$ is a very large number, and it contains a lot of factors of $2$, $3$, and other prime numbers. In fact, for any prime number $p \le 2004$, $2004!$ contains at least one factor of $p$.

Consider the prime factorization of $2004!$:
\[ 2004! = 2^{k_2} \cdot 3^{k_3} \cdot 5^{k_5} \cdot \ldots \cdot p^{k_p} \cdot \ldots \]

where $k_p$ is the number of times the prime number $p$ appears in the prime factorization of $2004!$.

The sum of divisors $S$ can be calculated using the formula:
\[ S = (1 + 2 + 2^2 + \ldots + 2^{k_2}) \cdot (1 + 3 + 3^2 + \ldots + 3^{k_3}) \cdot \ldots \cdot (1 + p + p^2 + \ldots + p^{k_p}) \cdot \ldots \]

Notice that each factor in the product is a geometric series, and it can be simplified as follows:
\[ 1 + p + p^2 + \ldots + p^{k_p} = \frac{p^{k_p + 1} - 1}{p - 1} \]

Now, consider the prime factorization of $2004$:
\[ 2004 = 2^2 \cdot 3 \cdot 167 \]

To find the remainder when $S$ is divided by $2004$, we need to find the remainder when each factor in the product is divided by $2004$.

For the factor corresponding to $p = 2$, we have:
\[ 1 + 2 + 2^2 + \ldots + 2^{k_2} \equiv 1 + 2 + 2^2 + \ldots + 2^2 \equiv 7 \pmod{2004} \]

For the factor corresponding to $p = 3$, we have:
\[ 1 + 3 + 3^2 + \ldots + 3^{k_3} \equiv 1 + 3 \equiv 4 \pmod{2004} \]

For the factor corresponding to $p = 167$, we have:
\[ 1 + 167 + 167^2 + \ldots + 167^{k_{167}} \equiv 1 + 167 \equiv 168 \pmod{2004} \]

For all other prime numbers $p$, the factor corresponding to $p$ is congruent to $1$ modulo $2004$, since $p$ does not divide $2004$.

Therefore, the product of all factors is congruent to:
\[ 7 \cdot 4 \cdot 168 \equiv 4704 \equiv \boxed{0} \pmod{2004} \]
