note 80386 added to function.fmod

I have this code for dividing two numbers: $dividend = "100200300400500"; $divident = "1000"; while ($dividend!="0") { $divisionRemainder = fmod($dividend, $divident); $answer = $dividend/$divident; $integralNumber = (int) $answer; $dividend = $integralNumber; }; For my is important know division remainder, because I need cut number 100200300400500...900... ect. on numbers with 3 number(100, 200, 300, 400... ect.) My code is good to number 100200300400 and if is number more biger than number 100200300400 (in size), division number is incorrect. For 100200300400 is answer 400, 300, 200, 100. For 100200300400500 is answer 500, 592, 52, 416, 1 ... this are bad numbres ... right is 500, 400, 300, 200, 100. Where is problem?
