Solution:

1)

$\\ \\ \dfrac{6}{19} \div 3 \\ \\ = \dfrac{ \dfrac{6}{19} }{3} \\ \\ = \dfrac{6}{19} \times \dfrac{1}{3}$

$\\ \\ = \dfrac{1}{3} \\ \\ = \dfrac{2}{19} \\ \\ = 0.105$

2)

$\\ \\ \dfrac{4}{5} \div 2 \\ \\ = \dfrac{\dfrac{4}{5} }{2 } \\ \\ = \dfrac{4}{5} \times \dfrac{1}{2}$

$\\ \\ = \dfrac{2}{5} \\ \\ = 0.4$

3)

$\\ \\ 12 \dfrac{7}{8} \div 6 \\ \\ = \dfrac{12 \times 8 + 7}{8} \div 6 \\ \\ = \dfrac{103}{8} \div 6$

$\\ \\ = \dfrac{ \dfrac{103}{8} }{6} \\ \\ = \dfrac{103}{8} \times \dfrac{1}{6} \\ \\ = \dfrac{103}{48} = 2.145$

4)

$\\ \\ 15 \dfrac{2}{3} \div 5 \\ \\ = \dfrac{15 \times 3 + 2}{3} \div 5 \\ \\ = \dfrac{47}{3} \div 5$

$\\ \\ = \dfrac{ \dfrac{47}{3} }{5} \\ \\ = \dfrac{47}{3} \times \dfrac{1}{5} \\ \\ = \dfrac{47}{15} \\ \\ = 3.133$

Basic points:

# While solving for fraction like a× b/c =

a×c+b/c

# While solving for, a/b ÷ c = a/b × 1/c

# Solve more such division questions to get good hold on it
