Divide...
You should have an image already opened. A small window named Multiply is opened. It enables to divide each pixel value by a constant factor (e.g. 1.25).
Division by zero is not allowed! This operation is not performed, but there is no warning.
This function is typically useful if you want to perform an operation on an image (e.g. to correct for a flatfield). See also the other operations proposed in the menu Process/Single Image Operators.
It is not used in the actual series of EU-HOU exercises.
