If $ \sum_{r=1}^{13}\frac{1}{r} = \frac{x}{13!}\;,$ Then the Remainder when $x$ is Divided by $11$ 
If $\displaystyle \sum_{r=1}^{13}\frac{1}{r} = \frac{x}{13!}\;,$ Then the Remainder when $x$ is Divided by $11$.

$\bf{My\; Try::}$ Given $\displaystyle \sum_{r=1}^{13}\frac{1}{r} = \frac{x}{13!}\Rightarrow 13!\left(1+\frac{1}{2}+\frac{1}{3}+................+\frac{1}{13}\right) = x$
So $\displaystyle x = \left(13!+\frac{13!}{2}+\frac{13!}{3}+.................+12!\right)$
Now How Can I solve after that
Help me
Thanks

Each term in your expression (each $\frac{13!}{k}$) is an integer, and except for the $k=11$ case is expressed as a rational fraction where the numerator contains a factor of 11 but the denominator does not.  Hence, each term except $k=11$ is 0 mod 11.  So the answer is going to be
$$
\frac{13!}{11} \mod 11 = (13 \cdot 12 \cdot \prod_{n=1}^{10}n) \mod 11 
= (2 \cdot 1 \cdot (-1)) \mod 11 = -2 \equiv 9 \mod 11  
$$
Here I used the fact (Fermat) that for $p$ prime, $p! \equiv -1 \mod p$
So the remainder will be 9.
