Given the numbers 628941 and 128378, to find the approximation of the division of 628941 by 128378, we perform the following calculations:
628941 \approx 629000
128378 \approx 128000
\frac{629000}{128000} = \frac{629}{128} \approx \frac{630}{130} = \frac{63}{13}
63 \div 13 = 4 \text{ remainder } 11
\frac{63}{13} \approx 4 + \frac{11}{13}
Since \frac{11}{13} is close to \frac{12}{13}, which is approximately 1, we have:
4 + \frac{11}{13} \approx 4 + 1 = 5
Therefore, the approximation of the division is 5.
