Move element with flexbox

Question

I can't move the last div inside the titolo class to the right.

Inside the div with the titolo class there are 5 more divs. The last div of these 5 should move to the right. I would like to avoid using the margin for moving

Can anyone help me please?

Thanks so much!!
