what is 52 million divided by 4.2 percent?

1238095238.0952380952380952380952380952380952380952380952380952380952380952

I don't know how you're doing to fit that in a maths book if you are of course!

$${ceiling}{\left({\frac{{\mathtt{52\,000\,000}}}{{\mathtt{0.042}}}}\right)} = {\mathtt{1\,238\,095\,239}}$$             

This is to the nearest whole number

what would you want to know that for?
