The mass of earth is approximately 7.97×10 24kilograms. The approximate mass of Venus is 417,000,000,000,000,000,000,000. About how many times greater is the mass of earth than the mass of Venus?

The gcd of 7970000000000000000000000 and 417000000000000000000000 is 1000000000000000000000, so 7970000000000000000000000/417000000000000000000000 = (1000000000000000000000×7970)/(1000000000000000000000×417) = 1000000000000000000000/1000000000000000000000×7970/417 = 7970/417:

417 | 7 | 9 | 7 | 0 |

- | 4 | 1 | 7 | |

| 3 | 8 | 0 | 0 |

- | 3 | 7 | 5 | 3 |

| | | 4 | 7 |

The quotient is 19 (the number on top of the bracket) and the remainder is 47 (the number at the bottom of the grid):

| | | 1 | 9 | (quotient)

417 | 7 | 9 | 7 | 0 |

- | 4 | 1 | 7 | |

| 3 | 8 | 0 | 0 |

- | 3 | 7 | 5 | 3 |

| | | 4 | 7 | (remainder) invisible comma

7970 = 19×417 + 47

The quotient of 7970/417 is 19 with remainder 47, so:

Answer: 19 47/417
