", because we don't want to pay ten times too much for anything, nor do we want to get only one-tenth of what we need! In this case, we will multiply the divisor by 10, and then we need to treat the dividend in the same way. Double and subtract the last digit in your number from the rest of the digits. Q What do you do with a remainder when dividing decimals? 6 x 2 x 2 . Solution: In this case, the divisor is a whole number so we need not make any changes. The number of circled groups is your answer, or quotient. Subtract 14 from 35 to get 21, which is divisible by 7, and we can now say that 357 is divisible by 7. By Sean Conaty. ThoughtCo, Apr. A simple way to do this is to simply put the divisor (for example, 2 is the divisor in 1 divided by 2) on the bottom and the dividend (1 is the dividend in 1 divided by 2) on top. Line up the quotient carefully so the decimal point falls into place:

\r\n\r\n

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.

\r\n\r\n\r\n

Multiplying and dividing - KS2 Maths - BBC Bitesize Here, the dividend is a decimal number and the divisor is a whole number, so the decimal point in the quotient will be placed according to the decimal point of the dividend.

At the same time, move the decimal point in the dividend (6.7) one place to the right:

   \r\n\r\n

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

   \r\n\r\n

   Now youre ready to divide:
