486 divided by three equals what?

How are we going to find out how many threes are in this three-digit number? We can use the short division method, 486 divided by three. Let’s go through each digit from left to right. How many threes are in four? If we divide four by three, we get an answer of one with a remainder of one. So we can write the remainder there.

Now that we’ve written the remainder, the eight has become 18. How many threes are in 18? There are six threes in 18. And this time, there’s no remainder. On to our final digit, how many threes are in six? What is six divided by three? Six divided by three equals two.

Because we couldn’t see a quick way to work out the answer mentally, we used the short division method. 486 divided by three equals 162.
