-	// The picoChip instruction set has a divstep instruction which
-	// is used to perform one iteration of a binary division algorithm.
-	// The instruction allows 16-bit signed division to be implemented.
-	// It does not directly allow 16-bit unsigned division to be
-	// implemented. Thus, this function pulls out the common division
-	// iteration for 15-bits unsigned, and then special wrappers
-	// provide the logic to change this into a 16-bit signed or
-	// unsigned division, as appropriate. This allows the two
-	// versions of division to share a common implementation, reducing
-	// code size when the two are used together. It also reduces
-	// the maintenance overhead.
-
-	// Input:
-	//	r0 - dividend
-	//	r1 - divisor
-	// Output:
-	//	r0 - quotient
-	//	r1 - remainder
-	// R5 is unused
-	
-	// Check for special cases. The emphasis is on detecting these as
-	// quickly as possible, so that the main division can be started. If 
-	// the user requests division by one, division by self, and so on
-	// then they will just have to accept that this won't be particularly
-	// quick (relatively), whereas a real division (e.g., dividing a 
-	// large value by a small value) will run as fast as possible
-	// (i.e., special case detection should not slow down the common case)
-	//
-	// Special cases to consider:
-	//
-	//	Division by zero.
-	//	Division of zero.
-	//	Inputs are equal
-	//	Divisor is bigger than dividend
-	//	Division by power of two (can be shifted instead).
-	//	Division by 1 (special case of power of two division)
-	//
-	// Division/modulus by zero is undefined (ISO C:6.5.5), so
-	// don't bother handling this special case.
-	//
-	// The special cases of division by a power of 2 are ignored, since 
-	// they cause the general case to slow down. Omitting these
-	// special cases also reduces code size considerably.
-
-	// Handle divisor >= dividend separately. Note that this also handles
