Yes. If we wanted to divide 104 by 8 we could write 104 as sum of multiples of 8 with which we are familiar:
104=80+24
then
We use the same procedure to divide the given number by 8:
First We can "decompose" the number as a sum of multiples of 8 which we recognize easily. Then, divide each single one of them with 8.
That is
<span>8,101,265,822,784 = 8,000,000,000,000+100,000,000,000+1,000,000,000
</span>
+265,822,784
now decompose 265,822,784:
265,822,784=240,000,000+24,000,000+1,000,000+800,000+22,784
now decompose 22,784
22,784=16,000+6,784
decompose 6,784
6,784=6,400+384= 6,400+320+64
Thus:
8,101,265,822,784 : 8 =(8,000,000,000,000+100,000,000,000+1,000,000,000+240,000,000

=(1,000,000,000,000+12,500,000,000)+(125,000,000+30,000,000)
+ 3,227,848
=1,012,500,000,000+155,000,000+3,227,848
=1,012,655,000,000+3,227,848
=1,012,658,227,848
104=80+24
