Overview
Divides the values of two rasters on a pixelbypixel basis.
Notes
The order of the inputs are important since the first input is divided by the second input.
When a number is divided by zero, the output result is NoData.
If both inputs are integers, an integer division is performed, and the output result is an integer. If either input is floating point, a floatingpoint division is performed, and the output result is a floatingpoint value.
If both inputs are single band rasters, or one of the inputs is a constant, the output will be a single band raster.
If both inputs are multiband rasters, the function will perform the operation on each band from one input, and the output will be a multiband raster. The number of bands in each multiband input must be the same.
If one of the inputs is a multiband raster and the other input is a constant, the function will perform the operation against the constant value for each band in the multiband input, and the output will be a multiband raster.
If both inputs are multidimensional rasters with same number of variables, the function will perform the operation for all slices with same dimension value, and the output will be a multidimensional raster. The variables in the inputs must have same dimensions or a common dimension but no uncommon dimensions.
If one of the inputs is a multidimensional raster and the other input is a constant, the function will perform the operation for all slices for all variables against the constant value, and the output will be a multidimensional raster.
Parameters
Parameter name  Description 

Raster  The input whose value will be divided by the second input. A number can be used as an input for this parameter, provided a raster is specified for Raster2. 
Raster2  The input whose value the first input will be divided by. A number can be used as an input for this parameter, provided a raster is specified for Raster. 
Extent Type  Choose which extent should be used in the output raster:

Cellsize Type  Choose which cell size to use in the output raster. If all the input cell sizes are the same, all the options will yield the same results.
