Use ecctools for this. in this ex dividing 2^60 pubkey:

Code:

priv 0x953f49ae70ed676 2**60

   953ec9ac70ed676
   753f49ae70ed676

/ 0x20000000 = dcf2e84ffffffffffffffffffffffffee73997ebdf8a334b693c56a1461840e7

- 1 - 0x4000 =
dcf2e84ffffffffffffffffffffffffee73997ebdf8a334b693c56a1461800e6

pub = 0217e6a9925b659b97394039c7f355150a7be9f3adcf797bc5681f8584af0a69a6

G replace your basepoint to this basepoint:

Enother code make 82 from 120 bit

You need find shitnumber and shit numbers with many pabkey or another method.

Use a inversion of 2^94 as a basepoint:

Code:

#modofy this code for work with publick key, it is easy.
N = 115792089237316195423570985008687907852837564279074904382605163141518161494337

def inv(v): return pow(v, N-2, N)
def divnum(a, b): return ( (a * inv(b) ) % N )

shitnim = 42782561

while shitnum2 < shitnim:
   #priv = (priv - x ) % N
   #print("pr",hex(priv))
   #priv1 = priv
   s =(divnum(priv,2**94)-(shitnim)) %N# -

   d = (divnum(shitnum2,2**94)) %N
   #if d > priv:
   #print(hex(d-priv % N))# +divnum(2**15,2**10)
   #x = d * 2**22 % N
   x = divnum(s,d)
   y= d * shitnum2
   #print("y",hex(y))
   df = (s - y )% N
   if x <2**82and x >= 0:
   print("New Priv x",hex(x),"d",hex(d),hex(df),"s",hex(s),"shitnum2",(shitnum2),"shit num", shitnim, "priv",hex(priv))



   shitnum2 = shitnum2 +1

output:

new priv is a divided priv - range 2^82, priv - 2^120.
