Answer :
To estimate the quotient of
$$802 \div 89,$$
we first focus on the divisor, which is $89$. A common estimation strategy is to round the divisor to a nearby number that is easier to work with.
1. Notice that $89$ is close to $90$, which is a round number.
2. Rounding $89$ to the nearest ten gives $90$.
3. Therefore, for estimation purposes, we can consider the division as
$$802 \div 90.$$
Among the options provided, the one that uses $90$ as the divisor is:
$$90 \longdiv{802}.$$
Thus, the best way to estimate before dividing $802 \div 89$ is to use $90$, and the correct answer is:
$$90 \longdiv{802}.$$
