Explain how to do 666 divided by 1000?

Answer 1

0.666

Answer 2

Long division:

# 1000 fits into 666 zero times, so write a decimal point, than add a zero to 666. # 1000 fits into 6660 six times, so write a 6 after the point, then subtract 1000*6 from 6660 and add a zero: 6600. # 1000 fits into 6600 six times, so write another 6, then subtract 6000 from 6600 and add a zero: 6000. # 1000 fits into 6000 six times, so write a third six and subtract 6000 from 6000. The remainder is zero, so now you're done. Your answer should look like: 0.666.

Decimal place trick:

Any time you multiply or divide a number by 1 (100) 10 (101), 100 (102), 1000 (103), or ten to any power, the number remains the same except for the decimal place. Multiplying by ten moves the decimal point one to the right, so 13.*10 =130. Dividing moves the point to the left, so 13./10 = 1.3. One hundred moves the point two places, one thousand moves it 3, and so on. So 666. divided by 1000 moves the point 3 spaces to the left:

# 66.6 # 6.66 # 0.666 Which is the same result as before. If you wanted to divide 666 by 1013, simply move the decimal left 13 spaces so you would get 0.0000000000666
