864 ÷ 24
Today we'll divide a big number by a two-digit number using long division. Let's try eight hundred sixty-four divided by twenty-four.
Write twenty-four outside the long division house, and eight hundred sixty-four inside.
Start on the left. Can twenty-four fit inside eight?
No — eight is too small. So we look at the first two digits, eighty-six, instead.
How many groups of twenty-four fit in eighty-six?
Three groups! Three times twenty-four is seventy-two, and four times would be ninety-six — too big. Write three on top.
Multiply: three times twenty-four is seventy-two. Write seventy-two underneath eighty-six.
Subtract: eighty-six minus seventy-two is fourteen.
Bring down the next digit, the four, to make one hundred forty-four.
How many twenty-fours fit in one hundred forty-four?
Exactly six! Six times twenty-four is one hundred forty-four. Write six on top.
Write one hundred forty-four underneath.
Subtract: one forty-four minus one forty-four is zero. No remainder!
Eight hundred sixty-four divided by twenty-four is thirty-six. Great work!
