The mass of SO2 is 32 + 16 + 16 = 64.
Therefore 64 grams is equal to one mole of SO2.
One mole of SO2 contains 1 mol of S and 1x2 mol of O since O has a subscript 2.
That means that there are 2 moles of O atoms in the compound.

Find the number of moles of SO2 by multiplying the 64.0 by the inverse of the molar mass (to cancel the units properly). Then take whatever the percentage of oxygen is in an SO2 molecule, something really close to 50%, and multiply that by the number of moles.

2 moles of oxygen atoms, as 64 grams of SO2 is one mole of SO2.
