I came across a shapefile (no information available about the original CRS) with some unknown Reference System (City of Stuttgart in Germany). Example of coordinates looks like 3465878, 5482952. I assume it is lat/lon.

How can I change the CRS to the decimal system of WGS84 with QGIS 3?

Is it possible to overlay it to another shapefile with the borders and match the CRS?

I would suggest double-checking if suddenly there is a prj-file, placed in the shapefile location.

If not, you can try using projfinder. For instance, when one tried it with provided coordinates (3465878, 5482952)

There are two most probable choices:

• 
  EPSG:31467 Name:DHDN / 3-degree Gauss-Kruger zone 3, as was mentioned by @MrXsquared


• 
  EPSG:31463 Name:DHDN / 3-degree Gauss zone 3 (deprecated)

I would proceed with EPSG:31467 because EPSG:31463 is not maintained anymore.

DHDN / 3-degree Gauss-Kruger Zone 3

WGS84 Bounds: 7.5000, 47.2700, 10.5000, 55.0600

Projected Bounds: 3386564.9400, 5237917.9109, 3613579.2251, 6104500.7393

I am pretty sure this is GK3 (EPSG:31467).

Go to layer properties --> Source and set source CRS to EPSG:31467

Then do the transformation (Export as...) to WGS84.

If everything is located perfectly, you are good to go. (If not, I was wrong about the CRS...)
