This number is called an epoch in debian packaging terms ...

If during the lifetime of a package someone made a mistake in numbering
or the upstream version handling changed massively, a package
maintainer can introduce an epoch ...

dpkg/apt are only capable of moving forward and the package version is
a critical bit for deciding what forward/backward means.

So if upstream changes its versioning schema or a packager made a
mistake so that the version would actually go backwards, apt would
simply not consider to update a package.

In such a case a maintainer can introduce an epoch to keep the version
going forward, you can easily spot these by the colon in the version
string and should ignore it when wanting read the actual version ...
