1. When doing long division can the remainder be 0?

Yes! When the remainder is 0, it means that the divisor is a FACTOR of thedividend.

This leads on to the next topic, the Factor Theorem.

2. What use is long division in algebra?

Skills in long division of whole numbers are not as essential in the days of calculators and computers.

Long division in algebra is still useful in evaluating limits, finding asymptotes and factorising polynomials, to state but a few.
