2162 ARITHMETIC

Divide 6.4938 by .242.

Multiply both dividend and divisor by 1000 by moving the decimal point three places to the right, thus making the divisor a whole number.

When the dividend does not contain the divisor evenly, add ciphers and continue to divide.

Ciphers added to the right of a decimal point do not change the value of a number.

Three decimal places in the quotient are usually sufficient.
