Significant figures are the number of digits in a number. To count the significant figures we must take into account that the zeros before the digit should not be counted, but the intermediate zeros or after the digit should be counted.

Now, when we do the two-digit division, the significant figures of the quotient will be equal to those of the digit with the fewest number of significant figures. Let's see what are the figures of the terms of the division and the final result:

We see that the quotient of the division is 0.746899..., but we have to write the answer only with 3 significant figures. If the number after the last figure to which we want to approximate is greater than 5, we must add 1 to the last figure, so the result will be: 0.747.

Answer: 0.747
