Interesting, but the primitive is digitDiv:neg: , not \\\
Why wouldn't the primitive be reported on the Smalltalk stack?

By the way, \\\ is not really usefull anymore.
The main difference is that \\\ avoids a normalization of the result.
Please note that you should not use it with negative receiver or argument.
Also note that \\ should be faster for Small Integers and for LargeInteger
up to 64 bits (we now have a primitive for that)
For LargeIntegers > 64 bits, \\ will be a bit longer because we pass thru a
primitiveFail before  calling same primitive than \\\, and then normalize
quotient and remainder.
