#(6x^3+10x^2+x+8)/(2x^2+1) = 3x+5# with remainder #(-2x+3)#

Explanation:

Using polynomial long division:
#{: (,,3x,+5,,), (,,"----","----","----","----"), (2x^2+1,")",6x^3,+10x^2,+x,+8), (,,6x^3,,+3x,), (,,"----","----","----","----"), (,,,10x^2,-2x,+8), (,,,10x^2,,+5), (,,,"----","----","----"), (,,,,-2x,+3) :}#
