First let's factor 9
Therefore we can write 9 as
[tex]9=3\times3[/tex]
But if we want with 1 as a factor we must write is just like
[tex]9=9\times1[/tex]
Which seems trivial, because
[tex]180000\div9\div1[/tex]
Is true, therefore, if we want 1 included in the division the answer would be
[tex]180000\div9\div1[/tex]
