Installation
Installing ckeditor is a multi-step process that cannot be done using the normal "Install new module" method. You will likely need FTP access your Drupal installation on the server. To help avoid confusion, read this: The ckeditor module archive available for download here is only a "wrapper" for the most recent ckeditor module archive, which you must separately download from the http://ckeditor.com site.
Step 1) Download and unpack the "wrapper" archive below to the sites->modules subdirectory of your Drupal 7 installation. This unpack creates a ckeditor 'module' folder which also contains a folder called ckeditor. This second ckeditor folder contains a text file that instructs you to install the most recent ckeditor archive *contents* from http://ckeditor.com into this almost empty ckeditor folder.
Step 2) Download the most recent ckeditor archive from the http://ckeditor.com site and unpack it in the sites->modules->ckeditor->ckeditor subdirectory of your Drupal 7 installation.
In the end you should now have the unpacked http://ckeditor.com archive files in the sites->modules->ckeditor->ckeditor subdirectory. These files include yet another ckeditor subdirectory which actually contains key files, such as ckeditor.js. When correctly installed the path to this key file should now be sites->modules->ckeditor->ckeditor->ckeditor->ckeditor.js.
Step 3) You can now enable CKEditor from the Administration>>Modules page on your Drupal website as you normally do for other modules.

mkesicki commentedHi,
in step 2 you make small mistake. CKEditor library (its files) should go to sites->modules->ckeditor->ckeditor directory so the path to ckeditor.js is sites->modules->ckeditor->ckeditor->ckeditor.js.
We will check how to make documentation easier to understand but to be honest nobody complain to this moment.
Thank for your ideas.

Anna_CKSource commentedThe installation instructions were updated a while ago and now available on the official CKEditor for Drupal module documentation site: http://docs.cksource.com/CKEditor_for_Drupal/Open_Source
The installation instructions also mention issues like choosing the correct installation path as well as some troubleshooting information.
