After shifting the decimal to the end of divisor carry out normal division.
Divide a decimal number by another decimal number
When the divisor is a decimal number, move decimal point towards right to make it a whole number. Shift the decimal point of dividend by the same number of places(as for divisor). So, here we shift decimal points of dividend and divisor to two places on the right. Thus it is a division of 722.4÷8 which will give the answer 90.3
