DIVIDE DAX Function (Math and Trig)
Safe Divide function with ability to handle divide by zero case.
Optional. The alternate result to return when dividing by zero.
Result of the division between Numerator and Denominator, or AlternateResult in case there is a division by zero.
Alternate result on divide by 0 must be a constant. By default, the AlternateResult argument is BLANK.
DIVIDE is faster than an IF statement checking whether the denominator is zero. However, DIVIDE is executed in the formula engine and it is not as fast as a native division.

-- DIVIDE performs safe division protecting from division by -- zero. In case of zero denominator, it returns its third -- argument that defaults to a blank.
