Welcome to the forums Bill!

Is there a window where you want to install the door? what is above where the door will go? You need a header or lintel above the opening in order to support the load above.

Exactly how do to it is a little out of my area of expertise but besides cutting the hole for the door you need to install a concrete lintel wider than the opening supported by the block on each side. Some of the others should chime in later with better info for you.

That looks like an 8" or 12" thick concrete bloc wall the has steel and grout at about 4' on center. It does not appear to be loadbearing, but you have to provide support for the triangle of block above the opening. You will need a precast concrete or steel lintel of can build a block lintel in place to maintain the same appearance.

Get a steel door with a matching steel frame and the supplier will be able to provide some installation methods and tips. To get it done fast and cleanly, use an experienced contractor. Once you have the masonry opening size, he will cut out the area with at least one side falling on a mortar joint. You may have to remove some 1/2 block on each side to allow you to grout the frame rigidly in place. The resulting door will be as secure as the walls and provide almost the same fire resistance value, if required.
