621 ÷ 99 = 6.27
The line on top of 27 means that 27 is a repeating decimal.
6.27 = 6.272727272727
Example #2482 ÷ 99 = ?Step 1The number in the hundreds place or 4 is part of the answer. Therefore, write 4 down and then put a decimal point next to it: 4.Step 2Add 4 to 8282 + 4 = 86Put a line on top of 86 and put everything next to 4.
