Step 3: Divide and bring down the other digit in sequence. In order to divide a decimal number by 10, move the decimal point to the left by one place. Put your decimal point in the quotient directly above where it falls in 91.25:

Now youre ready to divide. Place the decimal point in the quotient above the decimal point in the dividend:

Divide, being careful to line up the quotient properly:

Remember to insert a placeholding zero in the quotient so that the decimal point ends up in the correct place.

    6.7 / 10.1 = 0.7. Multiply the divisor by as many 10's as we need, until it is a whole number. Remember to include the decimal point above the dividend bar in your answer. At the same time, move the decimal point in the dividend (6.7) one place to the right:

    The problem asks you to round the quotient to one decimal place, so fill out the dividend with trailing zeros to two decimal places:

    9.13 / 4.25 = 2.15. Russell, Deb. For example: 12123 (1+2+1+2+3=9) 9 is divisible by 3, therefore 12123 is too! This math video tutorial explains how to multiply and divide decimals the easy fast way all in your head without using a calculator. Line up the quotient carefully so the decimal point falls into place:

    Even though the division comes out even after you write the digit 6 in the quotient, you still need to add a placeholding zero so that the decimal point appears in the correct place.
