Bug in division

[peterolson]

The division

BigInteger.parse("12345678901234567890123456789012345678901234567890123456789012345678901234567890")
  .divide(BigInteger.parse("1234567890"))
  .toString()

should return

"10000000001000000000100000000010000000001000000000100000000010000000001"

but instead returns

"10000000000000000000000000000000000000000000000000000000000000000000000"

good catch!

        part._d.unshift(b_digits[--b_index]);
+       part._s = 1;
