844 is written DCCCXLIV in Roman numerals. That is 6 symbol groups added together, reading left to right from the largest value down.

How it breaks down

DCCCXLIV = 500 + 100 + 100 + 100 + 40 + 4 = 844
Group Value Subtraction Running total
D 500 — 500
C 100 — 600
C 100 — 700
C 100 — 800
XL 40 L − X 840
IV 4 V − I 844

Why the smaller symbol comes first

DCCCXLIV uses subtractive notation in 2 places: XL means L minus X, or 40; IV means V minus I, or 4. A smaller symbol placed before a larger one is subtracted from it rather than added, which is why IX is nine and not eleven.

Only six such pairs are valid — IV, IX, XL, XC, CD and CM. That restriction is what makes the notation unambiguous: IIII and IC both look like they should work, but neither is standard, and only one spelling of any number is correct.
