In terms of partition, 20 / 5 means the size of each of 5 parts into which a set of size 20 is divided. For example, 20 apples divide into five groups of four apples, meaning that "twenty divided by five is equal to four". This is denoted as 20 / 5 = 4, or 20 / 5 = 4. [2] In the example, 20 is the dividend, 5 is the divisor, and 4 is ...
Forming an alternating sum of blocks of three from right to left gives a multiple of 7 [5] [7] 1,369,851: 851 − 369 + 1 = 483 = 7 × 69. Adding 5 times the last digit to the rest gives a multiple of 7. (Works because (50 − 1) is divisible by 7.) 483: 48 + (3 × 5) = 63 = 7 × 9. Subtracting 2 times the last digit from the rest gives a ...
Decimal numbers are not divided directly, the dividend and divisor are multiplied by a power of ten so that the division involves two whole numbers. Therefore, if one were dividing 12,7 by 0,4 (commas being used instead of decimal points), the dividend and divisor would first be changed to 127 and 4, and then the division would proceed as above.
The root mil in million does not refer to the numeral, 1.

Mathematics portal; 1,000,000,000 (one billion, short scale; one thousand million or one milliard, one yard, [1] long scale) is the natural number following ...
the long scale — designates a system of numeric names formerly used in British English, but now obsolete, in which a billion is used for a million million (and similarly, with trillion, quadrillion etc., the prefix denoting the power of a million); and a thousand million is sometimes called a milliard. This system is still used in several ...
1,000,000,000,000, i.e. one million million, or 10 12 (ten to the twelfth power), as defined on the short scale. This is now the meaning in both American and British English. 1,000,000,000,000,000,000, i.e. 10 18 (ten to the eighteenth power), as defined on the long scale. This is one million times larger than the short scale trillion.
