670/1.35 multiply both top and bottom by 100 => 67000/135
then divide like normal
my suggestion is to make a table listing 135 multiplied by 1-9 so you can divide it quicker
135*1=135
*2=270
*3=405
etc
I know it seems like a lot of extra work but its worth doing especially when you concider you learn more of your times tables and if you have a lot to do without a calculator. We didnt have calculators when I was a kid so its really not that bad and it really does help in the long run.
670/1.35=67000/135=1000*67/135=200*67/27=200*(2+13/27) = (about) 400+100=500.
if you don't know how to divide, then you need a calculator
67,000/135=496.29
$496.29
