1 Long Division Methods Method 1

2 We are going to try to solve
839 ÷ 27

3 Method 1 839 ÷ 27 8 3 9 (27 x 10 = 270)

4 Method 1 839 ÷ 27 8 3 9 (27 x 10 = 270) 5 6 9

5 Method 1 839 ÷ 27 8 3 9 (27 x 10 = 270) 5 6 9 (27 x 10 = 270) 2 9 9

6 Method 1 839 ÷ 27 8 3 9 (27 x 10 = 270) 5 6 9 (27 x 10 = 270) 2 9 9 (27 x 10 = 270) 2 9

7 Method 1 839 ÷ 27 8 3 9 (27 x 10 = 270) 5 6 9 (27 x 10 = 270) 2 9 9 (27 x 10 = 270) 2 9 (27 x 1 = 27) 2

8 Method 1 839 ÷ 27 8 3 9 (27 x 10 = 270) 5 6 9 (27 x 10 = 270) 2 9 9 (27 x 10 = 270) 2 9 (27 x 1 = 27) 2 = 31

9 Method 1 = 3 1 r 2 839 ÷ 27 Or 27

10 Long Division Methods Method 2

11 We are going to try to solve
839 ÷ 27

12 Method 2 839 ÷ 27 becomes 27 )

13 Method 2 27 x 10 = 270 Miles off! 839 ÷ 27 27 )

14 Method 2 27 x 10 = 270 27 x 20 = 540 Getting better! 27 ) 8 3 9
839 ÷ 27 27 )

15 Method 2 27 x 10 = 270 27 x 20 = 540 27 x 30 = 810 Much better!
839 ÷ 27 27 )

16 Method 2 27 x 30 = 810 Put the 810 underneath. 27 ) 8 3 9 - 8 1 0
839 ÷ 27 27 ) 2 9 27 x 30 = 810

17 Method 2 839 ÷ 27 27 ) 2 9 27 x 30 = 810 - 2 7 27 x 1 = 27 2

18 Method 2 839 ÷ 27 27 x 30 = 810 3 1 27 x 1 = 27 27 ) 2 9 = 31 - 2 7 2

19 Don’t forget the remainder! - 2 7 2
Method 2 839 ÷ 27 3 1 r 2 27 ) 2 9 Don’t forget the remainder! - 2 7 2

20 Method 2 = 3 1 r 2 839 ÷ 27 Or 27

21 Long Division Methods Method 3

22 We are going to try to solve
839 ÷ 27

23 Method 3 839 ÷ 27 becomes 27 )

24 Method 3 Calculate 8 ÷ 27 839 ÷ 27 27 )

25 We can’t do it, so we write the answer 0 here
Method 3 We can’t do it, so we write the answer 0 here 839 ÷ 27 27 )

26 Use you repeated subtraction here if this helps
Method 3 So we next look at 83 ÷ 27 839 ÷ 27 27 ) Use you repeated subtraction here if this helps

27 Method 3 2 x 27 = 54 3 x 27 = 81 839 ÷ 27 3 27 )

28 We need to take off 81 from the 83 to get the remainder 3 27 ) 8 3 9
Method 3 3 x 27 = 81 839 ÷ 27 We need to take off 81 from the 83 to get the remainder 3 27 ) - 8 1 2

29 Drop the next digit next to the 2 3 27 ) 8 3 9 - 8 1
Method 3 839 ÷ 27 Drop the next digit next to the 2 3 27 ) - 8 1 2 9

30 Now we are going to do 29 ÷ 27 and put the answer here
Method 3 Now we are going to do 29 ÷ 27 and put the answer here 839 ÷ 27 3 1 27 ) - 8 1 2 9

31 Now we are going to do 29 - 27 to get the remainder
Method 3 Now we are going to do to get the remainder 839 ÷ 27 3 1 27 ) - 8 1 2 9 2 7

32 Method 3 839 ÷ 27 3 1 r 2 27 ) - 8 1 2 9 2 7 2

33 Method 3 = r 2 839 ÷ 27 or 31 2 27
