Support for Office 2013 versions of Office 365 has ended. It is no longer available for download from the portal.
However, there are good cases when you do require Office 2013, ie. if your current line of business does not support Office 2016, or if you have older macros that are not supported on Office 2016.
HowTo-Outlook has posted some links on downloading Office 2013 if you still require this. The article can be found here – https://www.howto-outlook.com/howto/download-office-2013-office-365.htm
Here are direct links to the 32-bit English US versions.
