I chose not to have the estimated tax forms printed, but because of that I do not know what I should be paying quarterly. Do I simply divide the amount I paid this year by four?

Yes, you can take the total taxes paid for 2016 (line 63) and divide by 4.

You will pay or expect to pay (through withholding or other) 100% of 2016's taxes paid (110% if AGI is more than $150,000) or 90% of the 2017 taxes due.
