Question

what is the quotient?
1,521 ÷ 3 =
\overline{\quad\quad}
\

$$\begin{array}{r}\ 3\\enclose{longdiv}{1\\ 5\\ 2\\ 1}\ \\end{array}$$

Explanation:

Step1: Divide 15 (thousands and hundreds place) by 3

$15 \div 3 = 5$, so we write 5 in the hundreds place.

Step2: Bring down the 2 (tens place)

Now we have 2, but 2 is less than 3, so we write 0 in the tens place.

Step3: Bring down the 1 (ones place) to make 21

$21 \div 3 = 7$, so we write 7 in the ones place.
Putting it all together, the quotient is 507.

Answer:

507
