If you're not using a calculator, then it is best to convert the decimals to fractions:

17.8--> 17 and 8/10= 178/10

3.1--> 3 and 1/10= 31/10

So now it is easier to do the division: 178/10 ÷ 31/10= 178/10 × 10/31 as multiplying by the reciprocal (flipping the fraction around) is the same as dividing by the original.

So this gives 178/10 × 10/31= 1780/310=178/31=5.74
