Teach to divide by three figures

The division It is getting more and more complicated and for you to see in this video I will teach you how to divide by three digits. Division is one of the basic operations of elementary arithmetic. It consists of verifying how many times there is a number contained in another, it is the inverse operation of multiplication. It is necessary to know multiply correctly and with ease to be able to divide.

In order to divide by three digits We will follow the same procedure as for dividing by one and two figures. The only difference is that in the divisor there will be a three-digit number and this means that the multiplications that we will have to do to solve the division will be longer.

In order to divide by three digits We will have to look for a number that multiplied by the divisor gives us the dividend as a result. If there is no such number, we will look for another that multiplied by the divisor is close to the dividend but without going over. We will do this process throughout the division until we reach the remainder, which may be zero (exact division) or different from zero (inexact division).

Conceptually, division describes two related but different notions, that of separating and that of sharing. In a formal way, the division It is a binary operation that associates the product of the first by the inverse of the second with two numbers. For a nonzero number, the function division by that number is the reciprocal of multiplication by that number.

To practice everything I have learned in this video I have prepared some printable exercises with their solutions with three-digit divisions similar to those explained in class. I hope they help you improve the division!
