•49÷6=
•80÷9=

$57÷6=9······3$
$\begin{array}{r}9\\6\enclose{longdiv} {57}\\54\\\hline3\end{array}$
$37÷5=7······2$
$\begin{array}{r}7\\5\enclose{longdiv} {37}\\35\\\hline2\end{array}$

$49÷6=8······1$
$\begin{array}{r}8\\6\enclose{longdiv} {49}\\48\\\hline1\end{array}$
$80÷9=8······8$
$\begin{array}{r}8\\9\enclose{longdiv} {80}\\72\\\hline8\end{array}$

3.在括号里填上合适的数。
() ÷9=8……2 27÷()=3……3 65÷8=()……1
() ÷4=3……2 38÷()=6……2 18÷()=2……4
() ÷7=1……5 50÷()=5……5 74÷8=()……2
() ÷9=7……1 28÷()=3……1 19÷()=3……1
() ÷8=7……4 25÷()=3……4 43÷6=()……1

$(74)÷9=8······2$
$27÷(8)=3······3$
$65÷8=(8)······1$
$(14)÷4=3······2$
$38÷(6)=6······2$
$18÷(7)=2······4$
$(12)÷7=1······5$
$50÷(9)=5······5$
$74÷8=(9)······2$
$(64)÷9=7······1$
$28÷(9)=3······1$
$19÷(6)=3······1$
$(60)÷8=7······4$
$25÷(7)=3······4$
