MATHEMATICS FOR AIR CREW TRAINEES 7 e. Symbols.-"4,647 divided by 6" may be indicated in symbols in several ways. The division sign may be used: 4,647÷6. The "stroke" is more convenient to use on the typewriter: 4,647/6. Finally, the division may be indicated as a fraction: 4647/6. The fact that 4,647 divided by 6 is 774 with a remainder of 3 may be written as "4647÷6=774+3/6" or "4647/6=774+3/6" or "4647/6=774+3/6." f. Decimal point. -To locate the decimal point in the quotient when decimal points are present in either the divisor or the dividend, move the decimal point in the divisor to the right of the right-hand figure. Then move the decimal point in the dividend to the right the same number of places that the point was moved in the divisor. When dividing, be careful to place the quotient so that each figure of the quotient is directly above the right-hand figure of the group of figures which were used in the dividend. Then the decimal point in the quotient will be directly above the new position of the decimal point in the dividend. It will also be helpful to remember that the number of decimal places in the quotient is equal to the difference between the number of decimal places in the dividend and divisor. (1)Example: Divide 4.644 by .06 Solution: [[image]] Figure 12. (2)Example: Divide 6.646250 by 10.634. Solution: [[image]] Figure 13. g. If decimal points are involved in a division, as a rule the remainder is not indicated when the division does not come out even. In lieu thereof extra zeros are added to the dividend, and the division is continued until the quotient has as many figures as desired. 11
