    Purpose:        Perform extended-precision division
    Format:         opcode divr.rl,divd.rq,quo.wl,rem.wl
    Operation:      quo = divd/divr; rem = REM (divd, divr)
    C. Codes:       N = {quo LSS 0}, Z = {quo EQL 0}, C = 0,
                    V = {{integer overflow} OR {divr EQL 0}}
    Exceptions:     Integer overflow, divide by zero
    Opcode:         7B    EDIV     Extended divide
