$208$
$1872\div9$ is 208. Because the number ends in 72, you know that $1872$ is a multiple of 9. use long division. 9 goes into 18 twice, so the answer begins with 2. Subtract 18 and then solve 9 into 7. Since this does not work, add a 0 to the solution and bring down the 2. 9 into 72 is 8. So the solution is $208$.
