If you want to divide value need result as int then normally we use intval function but some case it give wrong result. This is simple code which result wrong

echo  intval(69.6  / .1);

Then final result is :

 Result :695 // which is wrong 
 Result will be : 696

so in this case first we need to make round value result then convert int, this is demo code which will work

echo  intval(round(69.6  / .1),2);

then the result is :

Result is : 696 // which is correct

So if you divide something then need result as int then use round function
