Shortcut to divide 2 digit by 9 steps

Let us see the steps now
Step 1: Enter the ten’s digit of the number as it is.
Step 2: To get the unit’s place digit add the ten’s place digit number and Unit’s place digit number and put the decimal point after the ten’s place digit.

Examples

Let us consider an example
Example 1:23÷ 9=?
Step 1: We enter the ten’s place digit as it is
Ten’s place digit=2
Step 2: We get the unit’s place digit by adding ten’s place digit and unit’s place digit
2+3=5
Unit’s place digit=5
Now add a decimal point between the unit’s place digit and the ten’s place digit to arrive at the answer
Ans          23÷ 9 =2.5
Example 2: 32÷ 9=?
Step 1: We enter the ten’s place digit as it is
Ten’s place digit=3
Step 2: We get the unit’s place digit by adding ten’s place digit and unit’s place digit
3+2=5
Unit’s place digit=5
Now add a decimal point between the unit’s place digit and the ten’s place digit to arrive at the answer
Ans          32÷ 9 =3.5
Example 3: 47÷ 9=?
Step 1: We enter the ten’s place digit as it is
Ten’s place digit=4
Step 2: We get the unit’s place digit by adding ten’s place digit and unit’s place digit
4+7=11.
Since it is a 2 digit number, add both numbers that is 1 + 1 to get unit’s place digit. We get, unit place digit=1+1=2
Also carry forward the ten’s place digit to step 1
Step 3: Add carry forward(1) from step 2 to original ten’s place digit of given number. we get, ten’s place digit= 4 + 1=5
Now add a decimal point between the unit’s place digit and the ten’s place digit to arrive at the answer
Ans          47÷ 9 =5.2
