Vertical segmentation

In the vertical calculation of division column, students often make few mistakes when they don't involve the calculation related to "0" (general calculation, not simple calculation), but once they learn the vertical calculation related to "0" (simple calculation), some students are prone to problems. Today, let's talk about the simple calculation related to "0" in vertical column.

First of all: divide 0 by any number that is not 0 to get 0. It is easy to understand that dividing 0 by a non-zero number is to divide 0 into several parts equally. Nothing, no matter how many parts it is divided into, so dividing 0 by any number that is not 0 will get 0.

The first type: the case where there is 0 in the middle of dividend. To put it simply, when there is a 0 in the middle of the dividend, there is no need to pull down 0 when dividing the column vertically, and 0 is directly the quotient on the head of 0. Then pull the next one.

Second, because the middle bit of dividend is not enough to divide quotient 0. In this case, if you don't score enough, just talk about the person who doesn't score enough, and then pull the person who doesn't score enough down with the one on the right.

The third is the case that there is a 0 at the end of the dividend, column vertical method: as long as the left side of the 0 at the end of the dividend is divided, the 0 at the end of the column vertical method does not need to be pulled down, and the quotient 0 ends directly at the head of the 0 at the end. Note that this simple method can only be used if the dividend to the left of the dividend at the end of 0 is divided.
