How to divide 4 ÷62 and show my work

Since the answer is to be correct to 1 decimal place, we need to continue the division to include 2 digits after the decimal point so that the final digit can be rounded correctly. Where necessary, additional zeroes after the decimal point have been added to allow for this.

Long division works from left to right. Since 62 is a 2-digit number, it will not go into 4, the first digit of 4, and so successive digits are added until a number greater than 62 is found. In this case 2 digits are added to make 400. Note the other digits in the original number have been turned grey to emphasise this and grey zeroes have been placed above to show where division was not possible with fewer digits.

The closest we can get to 400 without exceeding it is 372 which is 6 × 62.372 can be subtracted from 400 which gives a remainder of 28 but this is not essential now that we have reached 2 digits after the decimal point.

We need to check the final digit of 0.06 which is a 6. Since 6 is 5 or above the 1st digit after the decimal point must be rounded up to a NaN.

it is b)
