To divide a decimal by a whole number, divide as you would for whole numbers; and place a decimal point in the answer so that it lines up with the decimal point in the dividend.
Line up the numbers on the right, multiply each digit in the top number by the each digit in the bottom number (like whole numbers), add the products, and mark off decimal places equal to the sum of the decimal places in the numbers being multiplied. 9.683 ( 3 decimal places) x 6.1 ( 1 decimal place) 9683 (1 x 9683)
