I had to cheat
666 = 3*(0(2+1))*(377)
666 = (2+09)*(96+01)+1 666 = 3*(04+02+4*57)

Some more solutions for the last 4 digits:
11 = 9+(93)/3 12 = 9+933 13 = 9+(9+3)/3 15 = 9+9*33 17 = 9+93/3 18 = 9+9+33 19 = 9+9+3/3 I can't solve 14 or 16. I suspect they aren't possible. What do people think to allowing notation such as the following? 117 to 120 = 8*(2+5+8)  L4D[3 to 0] 121 to 133 = 8*(2+5+8) + L4D[1 to 13] It is fairly clear and saves a lot of typing and mistakes.

130 = (8+2)*(5+8) 144 = 8*(2*5+8) 160 = 8/(2/(5*8)) 168 = (8*2+5)*8 192 = 8*(25)*8 208 = 8*2*(5+8) <222 to 226 not covered> 240 = (82)*5*8 <254+ not covered> So we can fill in the gaps: 222 = 8*2*(5/(8/(9*9/3))3) 223 = 8+2*5*(8+9*9/(3+3))  Also can be 208+15 224 = 8*2*(5+8+9(93/3)) 225 = 8/(2/(5/(8/(9+9*3*3))))  I especially like this one with all the divisions, also can be 24015 226 = 8*2*(5+8+9/(93/3)) Last fiddled with by retina on 20190117 at 14:46

With the following suffixes we can span a stride of 9 (4 to +4)
0 = 93*3 1 = 9/3/3 2 = (93)/3 3 = 933 4 = (9+3)/3 And with the following prefixes we can cover 251 to 274 inclusive 255 = (8+2+5)*(8+9) 261 = (8*2+5+8)*9 264 = 8*(2+5*89) 268 = 8/(2/(58*9)) 270 = (8+25*8)*9

Feel free to use the ones that we have >13 or >4. Any additions to those lists may turn out to be useful.
If results could be posted using the notation I am using in the 1st post that would save me some time. I have added: 8 = 93/3 9 = 9+33 10 = 9+3/3 to the L3D list

No brackets required
275 = 8*2+5+8+9*9*3+3
