Yes, there is: the '//' operator.  :-)

There's no universally agreed upon definition for 'integer division' when negative numbers enter the mix, but I'm guessing that in this case you need something that rounds towards 0 instead of towards -infinity.  There's no dedicated operator for that, but you can simply do (assuming that b is positive):

   -(-a // b) if a < 0 else a // b
