$$[x]$$ is defined as the largest integer less than or equal to $$x$$, and $$ {x }=x-[x]$$.  For example, $$[4.3]=4$$, $$ {4.3 }=4.3-[4.3]=0.3$$.  $$[5]=5$$, $$ {5 }=5-[5]=0$$.  Find the value of $$\left { \frac{2018+1}{5} \right } + \left { \frac{2018+2}{5} \right } + \left { \frac{2018+3}{5} \right } + \cdots \cdots + \left { \frac{2018+2017}{5} \right } + \left { \frac{2018+2018}{5} \right }$$.
