• Carry the division as if the decimal (coma) does not exist
• Count the number of digits to the right of the decimal in each one (the number you dividing and the nuber you dividing by)
• Subtract the number of digits of the "devided by" number from the number of digits of the "divided" number
• If the result is positive Locate the decimal coma the same number of places from the extreme right of the result
• If the result is negative add the same number of zeros to the extreme right of the result

• Divide 12.8 by 6.4
• The initial result is 2
• The number of digits to the right of the decimal in the number you are "dividing" is =1
• The number of digits to the right of the decimal in the "divide by"  number is =1
• Subtract 1 from 1 the result is  0
• The final result will be 2

• Divide 6.25 by 2.5
• The initial result is 25
• The number of digits to the right of the decimal in the number you are "dividing"    is  2
• The number of digits to the right of the decimal in the "divide by"  number is =1
• Subtract 1 from 2 the result is 1
• The final result will be 2.5

• Divide 121 by 1.1
• The initial result is 11
• The number of digits to the right of the decimal in the number you are "dividing" is =0
• The number of digits to the right of the decimal in the "divide by"  number is =1
• Subtract 1 from 0 the result is -1 (negative)
• Add one zero to the initial result
• The final result will be 110

• Divide 12.1 by 11
• The initial result is 11
• The number of digits to the right of the number you are dividing is =1
• The number of digits to the right of the divide by number is =0
• Subtract 0 from 1 the result is +1 (positive)
• Place the decimal coma one digit to the left from the extreme right of the initial result
• The final result will be 1.1
