Step-by-step explanation:
See attached picture.
First, compare the highest term of the dividend (x²) to the highest term of the divisor (x).  We need to multiply the divisor by x.
When we do that, we get x² + 5x.  Subtracting this from the dividend, we get -9x + 11.
Now repeat the process.  Compare the highest term of the new dividend (-9x) to the highest term of the divisor (x).  We need to multiply by -9.
When we do that, we get -9x − 45.  When we subtract from the new dividend, we get 56.
So the quotient is x − 9, and the remainder is 56.
