The answer process is as follows:
(1) Step 1, write the dividend, divisor and divisor according to the calculation rules of vertical division, as shown in the following figure:
(2) The second step, starting from the high order of the dividend, first look at how many digits there are in the dividend, and then try to divide the first few digits of the dividend by the divisor. If it is smaller than the divisor, divide it by one digit as much as possible; Write the quotient except the dividend on the dividend. 4 is not enough to divide by 28. You need to see that 4,49,49 is divided by the next bit of 28, and you can write 1 in the tenth bit of 492, as shown below:
(3) Then multiply 1 by 28 and write the multiplication result under the corresponding number, as shown in the following figure:
(4) Difference: combine the result of 49-28 with the single digit of 492 to get 2 12, and then divide 28 by 2 12.
(5) If 2 12 is divided by 28, you can write 7 on each bit of 492, and then repeat the process of multiplication and difference to get 16, which is reserved as the remainder, as shown in the following figure:
