Question 1005024
Look carefully how the divisor is represented, and how the dividend is arranged:

<pre>
     3     |    -1     -7     6     0     -1
           |
           |           -3     -30   -72   -216
           |________________________________________
                -1    -10    -24    -72   -217
</pre>
Remainder is  {{{-217}}}.
The rest of the quotient represents a cubic polynomial.
