hi buddy i dont know any trick but i tried this on the calc a few times,u can covert the no into 1000000 or any close all zero no after the given no for that matter and then divide as the effects of rounding off will be visible after some 3 or 4 decimal places . take this for eg 100,00000 divided by 999989 is 10.00011 and if i divide it by 10,00000 then i get 10 hence the difference is only visible after 3 decimal places which i dont think would matter .
this is what i think and please do reply what happened with this and tell me any other technique if u are able to fathom out.
regards
