Long division: 70 goes into 58 0 times, remainder 58.
Bring down a zero: 580 ÷ 70 = 8, remainder 20.
Bring down a zero: 200 ÷ 70 = 2, remainder 60.
Bring down a zero: 600 ÷ 70 = 8, remainder 40.
Bring down a zero: 400 ÷ 70 = 5, remainder 50.
Bring down a zero: 500 ÷ 70 = 7, remainder 10.

Rounding
Rounded to a whole number the decimal is 1, to one decimal place 0.8 and to two decimal places 0.83. Round only at the end: rounding halfway through a calculation can change the last digit.
The formula explained
decimal = numerator ÷ denominator. The numerator is the top number and counts the pieces; the denominator is the bottom number and says how many equal pieces make a whole. Dividing the top by the bottom gives the size of the fraction as a decimal.
Another worked example: 12/5 as a decimal
- Simplify: 12/5 is already in simplest form
- Divide the numerator by the denominator: 12 ÷ 5 = 2.4
Equivalent fractions
58/70 has the same value as 116/140, 174/210 and 580/700: multiplying the top and bottom by the same number never changes a fraction. All of them give 0.8(285714) when divided out.
Comparing with nearby fractions
58/70 (0.8286) is bigger than 58/71 (0.8169) and smaller than 59/70 (0.8429). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.
The reciprocal
Flipping the fraction gives 70/58 = 1.(2068965517241379310344827586). A number multiplied by its reciprocal is always 1: 58/70 × 70/58 = 1.
