Why you don't try N-Bit_MATH?

I use this code to store result as string in array
Code:
'Convert 64Bit to string
    @  MOVE?CP  10, _Tmp64bit   ; copy a CONSTANT to a Pvar
    FOR i=19 TO 0 STEP -1
        @  MATH_DIV  _Int64Bit, _Tmp64bit, _Res64bit    ; Res = A / B;  Remainder in REG_Z
        ValueStr[i]=REG_Z+48
        @  MOVE?PP  _Res64bit, _Int64Bit                ; copy a Pvar to a Pvar
    NEXT i
