First the answer: 287176547.6 approx.
Now the explanation.
To get rid of the decimal point in the numerator we multiply top and bottom by 10000 because this number has 4 zeroes and there are 4 decimal places in the bottom: 24122830000/84.
4 goes into top and bottom: 6030707500/21.
Since 3×7=21 we can divide by 3 then 7: 6030707500/3=2010235833⅓.
Split the whole number and fraction and divide by 7 separately:
287176547+⁴⁄₇+¹⁄₂₁. Add the fractions together: ¹²⁄₂₁+¹⁄₂₁=¹³⁄₂₁.
So the complete answer is 287176547¹³⁄₂₁.
