First, write the coefficients of the polynomial in order of decreasing degree and include a placeholder for missing terms:

2 -8 -27 14 24

6

Bring down the leading coefficient:

2 -8 -27 14 24

6

2

Multiply the divisor by the result of the previous step and subtract from the corresponding coefficients:

2 -8 -27 14 24

6

2 -12

48

2 -12 21

-42

2 -12 21 -28

168

2 -12 21 -28 192

The result of the division is 2x³ - 12x² + 21x - 28 with a remainder of 192.
