Not really a question but..someone explain to me how to divide polynomials! i can’t get it

This is division:     for example, 5 divided by 2 is 2 with a remainder of 1. so the division statement is    if you did long division, you'd repeatedly subtract after multiplying 2 by some number, etc.polynomial long divisionsee the attachment headed with "polynomial long division" for examplevery similar to the normal long division with numbers.if we want to divide      then we can first set up the division symbols. the dividend, , goes inside and the divisor, x+2,  goes outside.when we do polynomial long division, we want to get rid of the highest x terms of the divisor.  we can multiply  by  to get  , and then subtract that from the dividend to get rid of the  term. then we repeat until we get something that is of a lesser degree than the divisor. it is very similar to long division with whole numbers.in the example, 15 is a polynomial with a degree of 0; the dividend is of a degree of 1. we stop there and that's our remainder.the quotient is  and remainder is 15.the division statement would look like    ======synthetic divisionsee attachment  headed "synthetic division" for exampleread it. when we get to the final step, we get this set of numbers:     starting from the right:     -62 is the remainder    25 is the coefficient on the  term, which is the constant    -8 is the coefficient on the  term    4 is the coefficient on the  termso the quotient is  with a remainder of  this example represented in quotient form is    which is
