Continue subtracting until the remaining number is less than the multiple, 6.

STEP 2

Subtract smaller multiples, such as 3 times the divisor until the remaining number is less than the divisor. In other words, keep going until you no longer a remainder is left in the place of the remainder. Then add the partial quotients to find the quotient.

So, there are 40 x 6 = 240 : 258 – 240 = 18

3 x 6 = 18 : 18 – 18 = 0

Therefore the quotient is 43 ( 40 + 3)

So, there are 100 x 4 = 400 : 692 – 400 = 392

4 x 50 = 200 : 392 – 200 = 192 : 4 x 48 = 192 : 192 – 192 = 0

Therefore the quotient is 198 ( 100 + 50 + 48)

Question 10.

Allison took 112 photos on vacation. She wants to put them in a photo album that holds 4 photos on each page. How many pages can she fill?

____ pages

Answer: 28 pages

Explanation:

STEP 1

Start by subtracting a greater multiple, such as 20 times the divisor.

Continue subtracting until the remaining number is less than the multiple, 4.

STEP 2

Subtract smaller multiples, such as 20 times the divisor until the remaining number is less than the divisor. In other words, keep going until you no longer a remainder is left in the place of the remainder. Then add the partial quotients to find the quotient.

So, there are 20 x 4 = 80 : 112 – 80 = 32

4 x 8 = 32 : 32 – 32 = 0

Therefore the quotient is 28 ( 20 + 8)
