How so i show my work with 624 divided by 3

We need to show how 624 divided by 3 works
First, let’s define each numbers:
=> 624 is the dividend
=> and 3 is the divisor
=> x = quotient

Now, let’s divide 624 by 3
How many 3’s are there in 624
=> 624 / 3
=> 208 , this is called the quotient

There are 208 3’s in 624, let’s check if our answer is correct.
=> 208 x 3
=> 624

Thus, x is equals to 208.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
