The way to solve the problem: first align the last digit of the two multipliers, then use the second multipliers respectively, multiply each digit by one multiplier in turn from the last digit, and finally accumulate the calculation results into products. If the multiplier is decimal, the corresponding multiple can be expanded first, and then the product can be reduced by the corresponding multiple;

Problem solving process:

Step 1: 3×93=279

Step 2: 1×93=930

Step 3: 8×93=74400

According to the above calculation results, the total is 75609.

Checking calculation: 75609÷8 13=93

Extended data/check calculation result: divide each bit of the dividend from the high bit, keep the quotient obtained from each calculation, add the next bit to the remainder for operation, and complete the operation of the dividend in this order, and combine the obtained quotients in order, and the remainder is the result of the previous operation.

Problem solving process:

Step 1: 7560÷8 13=9 and the remainder is: 243.

Step 2: 2439÷8 13=3 and the remainder is 0.

According to the above calculation steps, the comprehensive result is 93.
