Polynomial Long Division

A statistician was researching for a college / university and was wondering on average, how many students are enrolled in a college / university. The total number of enrolled college / university students in the United States from $2010$ to $2018$ can be modeled by the function $f(x) = x^{4}+6x^{2}+5$ and the number of colleges / universities in the United States can be modeled by the function $h(x)=x^{2}+5$. If $x$ is the number of years since $2010$, how many students, in average, are in one college / university?
