Write the problem in the special format:

25.020500

Step 1

How many 20's are in 5? The answer is 0.

Write down the calculated result in the upper part of the table.

Now, 5020=50=5.

Bring down the next digit of the dividend.

025.020500.0000.lll0.lll50.

Step 2

How many 20's are in 50? The answer is 2.

Write down the calculated result in the upper part of the table.

Now, 50220=5040=10.

Bring down the next digit of the dividend.

025.020500.0000.lll0.lll50.000.lll40.lll100.

Step 3

How many 20's are in 100? The answer is 5.

Write down the calculated result in the upper part of the table.

Now, 100520=100100=0.

Bring down the next digit of the dividend.

025.020500.0000.lll0.lll50.000.lll40.lll100.000.lll100.lll0.0

Step 4

How many 20's are in 0? The answer is 0.

Write down the calculated result in the upper part of the table.

Now, 0020=00=0.

025.020500.0000.lll0.lll50.000.lll40.lll100.000.lll100.lll0.00.0lll.0lll0

Since the remainder is 0, then we are done.
