304
Taking every number from 1 to 1000 inclusive, the number of digit 7s in the list totals 300.
There is one 7s orbital with two sub-orbitals: 7s(+1/2) and 7s(-1/2) . A picture of this 7s orbital is in 'Related links'
Two electrons (each with opposite spins) in the '7s orbital'
5.28751 7s equals 37.
8 / 7 in long division is however many 7s go into 8. so there's 1x 7 in 8 with 1 remainder. For this example, assume every number beyond is a 10, multiplied by the remainder. so, it'd be 7s into 10, which is 1 again. Then 7s into 30, which is 4. Then 7s into 20, which is 2. Then 7s into 60, which 8. Then 7s into 40, which is 5. Then 7s into 50, which is 7. And this is a reoccuring number, making it 1.142857142857 and so on.
7.143, approximately. 50 ÷ 7 = 7 with remainder 1
Expressed algebraically, this would equal 7s - 5.
