;* "div16u" - 16/16 Bit Unsigned Division
;*
;* This subroutine divides the two 16-bit numbers
;* "dd8uH:dd8uL" (dividend) and "dv16uH:dv16uL" (divisor).
;* The result is placed in "dres16uH:dres16uL" and the remainder in
;* "drem16uH:drem16uL".
;*
;* Number of words :19
;* Number of cycles :235/251 (Min/Max)
;* Low registers used :2 (drem16uL,drem16uH)
;* High registers used :5 (dres16uL/dd16uL,dres16uH/dd16uH,dv16uL,dv16uH,
