what are its divisions?
To divide 46785399 by 96431, the bars for the divisor (96431) are placed on the board.
Napier's bones
Division is performed in a similar fashion. To divide 46785399 by 96431, the bars for the divisor (96431) are placed on the board, as shown in the graphic below. Using the abacus, all the products of the divisor from 1 to 9 are found by reading the displayed numbers. Note that the dividend has eight digits, whereas the partial products (save for the first one) all have six.
where does the irrational number e come from The first references to the constant were published in 1618 in the table of an appendix of a work on logarithms by John Napier. who is this person? He was a Scottish landowner known as a mathematician, physicist, and astronomer. what is his contribution in the field of mathematics? He is the discoverer of logarithms, invented the so-called "Napier's bones" and made common the use of the decimal point in arithmetic and mathematics. what is this bone? It is a manually-operated calculating device for the calculation of products and quotients of numbers.

Napier's bones [SEP] Division
Division is performed in a similar fashion. To divide 46785399 by 96431, the bars for the divisor (96431) are placed on the board, as shown in the graphic below. Using the abacus, all the products of the divisor from 1 to 9 are found by reading the displayed numbers. Note that the dividend has eight digits, whereas the partial products (save for the first one) all have six. So the final two digits of 46785399, namely the '99', are temporarily ignored, leaving the number 467853. Then, the greatest partial product that is less than the truncated dividend is found. In this case, 385724.
