Traditionally, in order to multiply the given numbers we write the multiplicand (Whole number) and the multiplier (Powers of 10). The multiplication process consists of multiplying the multiplicand by each of the digits in the multiplier and writing each multiplication result on a separate line.
Dividing by powers of tenMove the decimal point right as many places as there are 0’s in the power. If there are not enough digits, add on 0’s. For example dividing 25 by 100, we want to choose the minimum number of digits from the dividend (25) such that the divisor (100) (powers of 10) is smaller than the number formed by these digits.
Since we have used all the digits of the divisor, we add a 0 next to the last remainder, 25. We are ready to divide this new number, 250, by the divisor, 100. We find that 100 goes into 250 no more than 2 times (100 x 3 = 300 is greater than 250, however 100 x 2 = 200 is less than or equal to 250), so we place a 2 above the 25 as the next digit in our quotient. We have already discovered that 100 goes into 250 no more than 2 times. We now calculate that 100 x 2 = 200, so we place 200 underneath 250. Now we must find the difference between 250 and 200. We subtract 250 minus 200 and write the result, 50 in the diagram. Observe that no minus sign is drawn in the diagram for this subtraction. Since we have used all the digits of the divisor, we add a 0 next to the last remainder, 50. We are ready to divide this new number, 500, by the divisor, 100. We find that 100 goes into 500 no more than 5 times (100 x 6 = 600 is greater than 500, however 100 x 5 = 500 is less than or equal to 500), so we place a 5 above the 25 as the next digit in our quotient. We have already discovered that 100 go into 500 no more than 5 times. We now calculate that 100 x 5 = 500, so we place 500 underneath 500. Now we must find the difference between 500 and 500.

How do you multiply and divide by powers of 10?To multiply by a power of 10, simply move the decimal to the right the same number of places as the exponent or as the number of zeros. Example: To divide by a power of 10, simply move the decimal to the left the same number of places as the exponent or as the number of zeros.
How do you multiply and divide by 10 100 and 1000?When we multiply by 10, 100 and 1000 we shift the digits to the left. One place left for 10, two places left for 100 and three places left for 1000. When we divide by 10, 100 and 1000 we do the opposite and shift the digits to the right instead.
