Let's break this down step by step:

17 1/18 converted to an improper fraction is 307/18.307/18 multiplied by 3.6 is approximately 53.905.0.476 divided by 14 is approximately 0.034.Subtracting the result from step 3 from the result in step 2 gives us 53.905 - 0.034 = 53.871.

Next, let's calculate the second part of the equation:

0.009 multiplied by 8700 is 78.3.120 divided by 4 2/7 is 120/(4 + 2/7) = 120/(4 + 9/7) = 120/(37/7) = 120 * 7/37 = 840/37.Subtracting this result from step 2 from the result in step 1 gives us 78.3 - 840/37 = 78.3 - 22.7027 = 55.5973.

Adding these two results together gives us:

53.871 + 55.5973 = 109.4683.

Finally, let's divide this result by 0.306 and then divide the result by 0.3:

109.4683 / 0.306 = 358.0246
358.0246 / 0.3 = 1193.4159

Therefore, the final answer is approximately 1193.4159.
