$0.8 \div 16 = \frac{8}{10} \div \frac{16}{1} = \frac{8}{10} \times \frac{1}{16} = \frac{1}{20}$

$25.3 \div 50 = \frac{253}{10} \times \frac{1}{50} = \frac{253}{500}$

$14.23 \div 25 = \frac{1423}{100} \times \frac{1}{25} = \frac{1423}{2500}$

$13.9 \div 10 = 1.39$

$645.3 \div 100 = 6.453$

$0.07 \div 1000 = 0.00007$

$9371.2 \div 50 = \frac{93712}{10} \times \frac{1}{50} = \frac{23428}{125}$

$37.2 \div 2.4 = \frac{372}{10} \times \frac{10}{24} = \frac{372}{24} = \frac{31}{2}$

$18.18 \div 5.05 = \frac{1818}{100} \times \frac{100}{505} = \frac{1818}{505} = \frac{18}{5}$

$181.04 \div 14.6 = \frac{18104}{100} \times \frac{10}{146} = \frac{18104}{1460} = \frac{62}{5}$

$183.6 \div 8.5 = \frac{1836}{10} \times \frac{10}{85} = \frac{1836}{85} = \frac{108}{5}$

$495.1 \div 0.2 = \frac{4951}{10} \times \frac{10}{2} = \frac{4951}{2}$
