calculator division VS long division?

lethalforce · 09-13-2006, 01:57 AM

why do calculators give a different answer than long division does when dealing with remainders?

for example if i do a problem like 232 divided by 5 i get 46.2 using LONG DIVISON

but when i do that same problem on a calculator i get 46.4?

why is that? i know my long division is right, this website proves it

The remainder is 2. That is a fraction, meaning 2/5 (the original number). Therefore, 46.4.

I think maybe a calculator leaves the remaining 2 as the remainder and does not divide it out.... I'm not completely sure though...

i don't understand, explain further would you?

You get a remainder of 2. That does not mean 0.2. Go further with the division, you will get 0.4.

A remainder is a fraction. You are dividing by 5. If you have a remainder of 2, that is put over 5 to give you 2/5, or 0.4.
