Hello! Schoolmate! 402÷49=8……The 10 quotient is 8, and the remainder is 10 columns, and the vertical calculation process is shown in the figure below.

This problem is a division with remainders, so when we calculate, if we can't divide it after the quotient, we must sell the branches to drop the remainder. And don't continue to deal with it anymore, this should belong to the remainder of the division of the land method.

The vertical calculation of 302 57 is as follows:

The process is as follows:

1) The first step is to write the dividend, divisor and division sign according to the calculation rule of the vertical division method, as shown in the figure below

2) The second step starts from the high position of the dividend, first see how many digits there are in the divisor, and then use the divisor to try to divide the first few digits of the dividend, if it is smaller than the divisor, try to divide by one more digit; Divide to the digit of the dividend, write the quotient on that digit. 30 is not enough to divide by 57, you need to see the next digit of 30 302, 302 divided by 57, you can write 5 on the single digit of 302, as shown in the following figure:

3) Then multiply 5 by 57, and the result of multiplication is written below the corresponding digits, as shown in the figure below

4) Make a difference, use 302-285, the result obtained is 17, which is reserved for the remainder, as shown in the figure below

My brother holds a book all day long, his short hair is short, and he has a pair of eyes on the bridge of his nose, and he is very tall.

My parents took me to my brother's house, and my brother walked out of the study with a book in his hand, and said hello to my parents: "Uncle, hello aunt." Mom and Dad also nodded again and again:

Good, good. After that, the elder brother returned to the study, sat on the sofa, crossed Erlang's legs, put the book on his lap, and began to read the book with relish again, and the guests were all under the care of the eldest mother. followed my brother into the study, "Wow!

The bookcase was filled with rows of books, and there were several boxes on the floor, which were also full of books. Classical classics, history, prose, **......As long as you can name the title, he will probably have it.

Xingjian went to grandma's house for dinner together, and when he came, he carried a bag in his hand, what was in the bag? It's not going to be a book again. Sure enough, as I expected, it was a book, outside of class, and in class.

As soon as my brother put down the bag, he took out a copy, what "Can mosquito blood really make dinosaurs?" What a novelty book!

After eating, the table was full of big fish and meat, but these dishes did not attract my brother, my brother served the rice, picked up the chopsticks and ate quickly, stirred the food together, and pulled it into his mouth, as if he was afraid that the dishes would be eaten up later. After eating, I put the chopsticks on the table, and I put up my legs to read the book, which has been replaced by another book, called "Curious African Animals and Plants". I said:

Did you finish reading one just now? He didn't hear it, he didn't hear the good-looking TV series next to him, and he didn't notice it when grandma gave us fruit.

On the way to the car, he took out a textbook from his bag, leaned on the back of the car seat, and concentrated. I thought: Won't my brother have a headache? The car is rocking, and it is no wonder that the eyes are short-sighted. He is really a book lover, and he loves to read books to this extent.

This is my book lover brother, who takes up books every minute and every second.

The calculation of vertical and curved seepage imitation is as follows:

Hello! 71 divided by 7 equals 10, and the remainder is 1. The mathematical formula is 71 7 = 10....1. The vertical division operation is shown in the figure below.

Vertical, refers to the change of each transition number from the previous transition number, the single digit of the previous transition number multiplied by 2, if you need to carry the digit, then advance to the front by 1, and then the single digit rises by 10 digits, and so on, and the single digit is filled with a new operation number.

For example, 42 is divided by 7, starting from 4 divided by high to low. When the division method is calculated vertically, it starts to divide from the highest digit, for example: 42 is divided from the highest ten digit 4; If you can't get rid of it, such as:

4 cannot be divided by 7, so divide by combining the highest digit and the next digit into a number until you can divide by the divisor; For example, if 42 is divided by 7 and 4 cannot be divided by 7, 4 and 2 are combined into a number 42 to divide 7, and the quotient is 6.
