[Tex/LaTex] How to insert page number in Beamer navigation symbols

beamerheader-footerpage-numbering

I created a presentation with Beamer, and I used Darmstadt theme.

But, this theme doesn't have the page number.

I know that I can insert the page number in Footline with:

\setbeamertemplate{footline}[frame number]

But, how can I insert the page number in "Navigation symbols", like this picture?

You can use something like

\addtobeamertemplate{navigation symbols}{}{%
    \usebeamerfont{footline}%
    \usebeamercolor[fg]{footline}%
    \hspace{1em}%
    \insertframenumber/\inserttotalframenumber
}

and use spaces, font and boxes to adjust the alignment of the numbers with the navigation symbols.

You can change the font/color just by altering the font/color for footline as in

\setbeamercolor{footline}{fg=blue}
\setbeamerfont{footline}{series=\bfseries}
