First put the large number inside the division bar and the smaller
number outside
For Example: 895 ÷ 5
8 9 55
Now try to divide the number in the hundreds column (8) by 5: In this case, the closest multiple of 5 is: 1 x 5 = 5
8 9 55
Now try to divide the number in the hundreds column (8) by 5: In this case, the closest multiple of 5 is: 1 x 5 = 5
8 9 55
The 1 is placed in the hundreds column directly above the 8
1
Now try to divide the number in the hundreds column (8) by 5: In this case, the closest multiple of 5 is: 1 x 5 = 5
8 9 55
The 1 is placed in the hundreds column directly above the 8
1
The 5 from 1 x5 = 5 goes directly below the 8 -5
Now try to divide the number in the hundreds column (8) by 5: In this case, the closest multiple of 5 is: 1 x 5 = 5
8 9 55
The 1 is placed in the hundreds column directly above the 8
1
The 5 from 1 x5 = 5 goes directly below the 8 -5
3The remainder, the difference between 8 & 5, goes under the 5
Now try to divide the number in the hundreds column (8) by 5: In this case, the closest multiple of 5 is: 1 x 5 = 5
8 9 55
The 1 is placed in the hundreds column directly above the 8
1
The 5 from 1 x5 = 5 goes directly below the 8 -5
3The remainder, the difference between 8 & 5, goes under the 5
The number from the tens column is then dropped down next to the 39
Now try to divide this new number (39) by 5: In this case, the closest multiple of 5 is: 7 x 5 = 35
8 9 551
-53 9
Now try to divide this new number (39) by 5: In this case, the closest multiple of 5 is: 7 x 5 = 35
8 9 55
The 7 is placed directly above the 9, in the TENS column
1
-53 9
7
Now try to divide this new number (39) by 5: In this case, the closest multiple of 5 is: 7 x 5 = 35
8 9 55
The 7 is placed directly above the 9, in the TENS column
1
The 35 from 7 x5 = 35 goes directly below the 39
-53 9
7
-3 5
Now try to divide this new number (39) by 5: In this case, the closest multiple of 5 is: 7 x 5 = 35
8 9 55
The 7 is placed directly above the 9, in the TENS column
1
The 35 from 7 x5 = 35 goes directly below the 39
-53
The remainder, the difference between 39 & 35, goes under the 35
9
7
-3 54
Now try to divide this new number (39) by 5: In this case, the closest multiple of 5 is: 7 x 5 = 35
8 9 55
The 7 is placed directly above the 9, in the TENS column
1
The 35 from 7 x5 = 35 goes directly below the 39
-53
The remainder, the difference between 39 & 35, goes under the 35
The number from the units column is then dropped down next to the 4
9

-3 54 5
Now try to divide this new number (45) by 5: In this case, 9 x 5 = 4 5
8 9 551
-53 9
7
-3 54 5
Now try to divide this new number (45) by 5: In this case, 9 x 5 = 4 5
8 9 55
The 9 is placed directly above the 5, in the UNITS column
1
-53 9
7
-3 54 5
9
Now try to divide this new number (45) by 5: In this case, 9 x 5 = 4 5
8 9 55
The 9 is placed directly above the 5, in the UNITS column
1
The 45 from 9 x5 = 45 goes directly below the 45
-53 9
7
-3 54 5
9
-4 5
Now try to divide this new number (45) by 5: In this case, 9 x 5 = 4 5
8 9 55
The 9 is placed directly above the 5, in the UNITS column
1
The 45 from 9 x5 = 45 goes directly below the 45
-53
In this question there is no remainder,
9
7
-3 54 5

-4 50 so 895 ÷ 5 = 179
Now try to divide this new number (45) by 5: In this case, 9 x 5 = 4 5
8 9 55
The 9 is placed directly above the 5, in the UNITS column
1
The 45 from 9 x5 = 45 goes directly below the 45
-53
In this question there is no remainder,
