We need to invert the denominator and then multiply, so we get
m^8
---
9
-------
m^13
---
18
becoming
(m^8 / 9) * ( 18 / m^13) =
2 / m^5
when the 9 and m^8 cancel...

Invert the denominator and multiply as follows:
[m^8/9]

Change the division problem into a multiplication by flipping the second fraction:
.
=(m^8/9)(18/m^13)
.
Cancel out the exponents by subtraction:
(m^8-8/9)(18/m^13-8)
=(1/9)(18/m^5)
.
Continue to cancel out:
(1/1)(2/m^5)
.
Multiply straight across:
2/m^5
