Divide 35 into 2 equal groups?
Step 1: Show 35 as 3 tens and 5 ones.
Draw 2 boxes for 2 equal groups.
Record:
2 35
Step 2: Place an equal number of tens in each group.
1 ten in each group
2 35
−
2 tens used
1 ten left
Step 3: Regroup the remaining tens and ones. So, regroup 1 ten and 5 ones as 15
ones. Place an equal number of ones in each group.

85 ÷ 6 = ____ R ___
Step 1: 85 = 8 tens + 5 ones
Divide the tens: 8 ÷ 6 = 1 R2
Step 2: Bring down the 5 ones.
Divide the ones: 25 ÷ 6 = 4 R1

Subtract: 8 – 6 = 2
Multiply: 6 × 4 = 24

Subtract: 25 – 24 = 1
The difference, 2, should be less than
the divisor, 6.

The difference, 1, should be less than
the divisor, 6.
87 ÷ 8 = ____ R ___
Step 1: 87 = 8 tens + 7 ones
Divide the tens: 8 ÷ 8 = 1 R0
Step 2: Bring down the 7 ones.
Divide the ones: 7 ÷ 8 = 0 R7

Multiply: 8 × 0 = 0
Subtract: 7 – 0 = 7
The difference, 0, should be less than
the divisor, 8.
The difference, 7, should be less than

Math Concept
If we divide a number by 10,
• the quotient is the number formed by removing the
digit in ones place
• the remainder is the digit in the ones place
For example,
67 ÷ 10 = 6 R 7
346 ÷ 10 = 34 R 6
Find the quotient and the remainder.
[1]
38 ÷ 10 = 3 R 8
quotient = 3, the number without the digit in ones place
remainder = 8, the number in the ones place
[2]
165 ÷ 10 = 16 R 5
quotient = 16, the number without the digit in ones place
remainder = 5, the number in the ones place
