For example, to change 1 / 4 to a decimal expression, divide 1 by 4 (" 4 into 1 "), to obtain exactly 0.25. To change 1 / 3 to a decimal expression, divide 1... by 3 (" 3 into 1... "), and stop when the desired precision is obtained, e.g., at four places after the decimal separator (ten-thousandths) as 0.3333.
