The name Isaiah in Hebrew letters is ישעיהו. Below: how its number adds up, which page of the Torah it falls on and what verse stands there. Everything is computed, nothing is guessed.
ישעיהו
In short
Your name in Hebrew letters is ישעיהו. “The Lord is salvation.” The prophet in Jerusalem of the eighth century BCE; his book is the longest of the prophets. Adding up the numbers of its letters gives 401 — the same as the Torah word את, “self”. That number points to Torah page 47 of 354 — in the portion Vayetzei. What that portion is about: The dream of the ladder to heaven; Jacob with Laban: Leah and Rachel; eleven sons are born; the return. The verse that begins with the first letter of your name and ends with the last is Genesis 9:27. Each of these steps is laid out below with its sources. There are no predictions or judgments here — only the text of the Torah and arithmetic you can check.
Adding up the letters of the name ישעיהו gives 401.
401
The number 401 is the Torah word את — «self» (Genesis 1:1).
The number 401, as the remainder modulo 354, points to Torah page 47 in the book of Bereshit (Genesis). These are its opening words:
ההוא בית אל ואולם לוז שם העיר לראשנה …
The verse this place falls on is Bereshit (Genesis) 28:19:
וַיִּקְרָא אֶת־שֵׁם־הַמָּקוֹם הַהוּא בֵּית־אֵל וְאוּלָם לוּז שֵׁם־הָעִיר לָרִאשֹׁנָה
And he called the name of that place Beth-el, but the name of the city was Luz at the first.
This is from the portion Vayetzei. What it is about: The dream of the ladder to heaven; Jacob with Laban: Leah and Rachel; eleven sons are born; the return.
The same number, 401, is given by these biblical names:

Nine ways of counting
The tradition counts the same name in several ways. The main one is above: each letter is its number. The other eight are old and checkable too; each gives its own number, and many of them have a Torah word with the same number.
Final letters as 500–900 (mispar gadol) — 401. A Torah word with the same number is את — “self” (Genesis 1:1).
Reduced, each letter to one digit (mispar katan) — 23.
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 68. A Torah word with the same number is חלל — “to bore, i.e.” (Genesis 4:26).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1566.
Squares of the letter values (mispar perati) — 95161.
Building: the sum grows with each letter (mispar bone’eh) — 1886.
The word that comes out is מבזמצפ. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 259. A Torah word with the same number is ראובן — “Reuben, a son of Jacob” (Genesis 29:32).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 548. A Torah word with the same number is מחצית — “a halving or the middle” (Exodus 30:13).
The number 401 appears in the classical books 6 times across 6 works. The earliest mention is שער הפסוקים (~1573).

The name ישעיהו does not stand as a word in the Pentateuch — as with most names, including many Tanakh names from the later books.
The verse of your name
There is a custom: at the end of the prayer one says a Torah verse that begins with the first letter of one's name and ends with its last. For ישעיהו these are י and ו. The Pentateuch has 7 such verses. The first of them is Genesis 9:27:
יפת אלהים ליפת וישכן באהלי שם ויהי כנען עבד למו
This is from the portion Noach. What it is about: The flood and the ark; the rainbow as a sign of the covenant; the tower of Babel; ten generations from Noah to Abraham.

Each Hebrew letter has a number; a word's number is their sum (alef 1 … tav 400). The page is the remainder modulo 354: the Torah divided into 354 pages of 861 letters, as the lunar year has 354 days. Everything can be checked by hand.
