What is the result of (3.59 m x 1.28 m)/ 0.88 m with the proper number of significant figures ?

Using a calculator I came up with:
Step 1. Multiplied 3.59 and 1.28, which equals 4.5952
Step 2. Divided 4.5952 by 0.88, which equals 5.221818182 m

If your m equals 1,000,000 then,
Step 3 multiply 5.221818182 by 1,000,000 which equals 5,221,818.182
