Hello
I will do my best to explain in "English" :
create a blank disk image of the required size.
My own choice is 5 times the size of the true numbers document
When it is created, you open it (of course, it will ask for the password).
you move the document in the white disk which will appear on the desktop.
You would be able to work with the file when the image disk is open.
Close it and its contents will be encrypted.
Next time, when you will try to open the disk image, you will be asked for the password again.
But I'm sure that Apple's wording, in the help or at:

is more clear 😉
