Now, 9−0⋅22=9−0=9.
Bring down the next digit of the dividend.
−040.9090922−90↓0.00000−000.0000lll0.lll90.
Step 2
How many 22's are in 90? The answer is 4.
Write down the calculated result in the upper part of the table.
Now, 90−4⋅22=90−88=2.
Bring down the next digit of the dividend.
−040.9090922−900↓.00000−000.0000lll0.lll90.−000.0000lll88.lll20.
Step 3
How many 22's are in 20? The answer is 0.

Now, 20−0⋅22=20−0=20.
Bring down the next digit of the dividend.
−040.9090922−900.0↓0000−000.0000lll0.lll90.−000.0000lll88.lll20.−00.00000lll0.lll20.0
Step 4
How many 22's are in 200? The answer is 9.
Write down the calculated result in the upper part of the table.
Now, 200−9⋅22=200−198=2.
Bring down the next digit of the dividend.
−040.9090922−900.00↓000−000.0000lll0.lll90.−000.0000lll88.lll20.−00.00000lll0.lll20.0−00.00000lll19.8lll20
Step 5
How many 22's are in 20? The answer is 0.
Write down the calculated result in the upper part of the table.
Now, 20−0⋅22=20−0=20.
Bring down the next digit of the dividend.
−040.9090922−900.000↓00−000.0000lll0.lll90.−000.0000lll88.lll20.−00.00000lll0.lll20.0−00.00000lll19.8lll20−00000lll0lll200
Step 6
How many 22's are in 200? The answer is 9.

Now, 200−9⋅22=200−198=2.
Bring down the next digit of the dividend.
−040.9090922−900.0000↓0−000.0000lll0.lll90.−000.0000lll88.lll20.−00.00000lll0.lll20.0−00.00000lll19.8lll20−00000lll0lll200−00000lll198lll20
Step 7
How many 22's are in 20? The answer is 0.
Write down the calculated result in the upper part of the table.
Now, 20−0⋅22=20−0=20.
Bring down the next digit of the dividend.
−040.9090922−900.00000↓−000.0000lll0.lll90.−000.0000lll88.lll20.−00.00000lll0.lll20.0−00.00000lll19.8lll20−00000lll0lll200−00000lll198lll20−000lll0lll200
Step 8
How many 22's are in 200? The answer is 9.
Write down the calculated result in the upper part of the table.
Now, 200−9⋅22=200−198=2.
−040.9090922−900.00000−000.0000lll0.lll90.−000.0000lll88.lll20.−00.00000lll0.lll20.0−00.00000lll19.8lll20−00000lll0lll200−00000lll198lll20−000lll0lll200−000lll198lll2
As can be seen, the digits are repeating with some period, therefore it is a repeating (or recurring) decimal: 90022=40.9¯09
Answer: 90022=40.9¯09
