The name Joshebbasshebeth in Hebrew letters is ישב. 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.
ישב
In short
Your name in Hebrew letters is ישב. A Tanakh name: an Israelite (first in 2 Samuel 23:8; 2 mentions in the Tanakh). Meaning, per Strong’s dictionary (1890): “sitting in the seat”. Adding up the numbers of its letters gives 312 — the same as the Torah word ישב, “to sit, dwell”. That number points to Torah page 312 of 354 — in the portion Eikev. What that portion is about: “Because you will heed”: the land of seven fruits; the blessing after meals; manna as a test; the second paragraph of the Shema. The verse that begins with the first letter of your name and ends with the last is Exodus 15:6. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Joshebbasshebeth” — this exact spelling is what was calculated: ישב. A name from the Tanakh — its Tanakh spelling is used. If your name is spelled differently, correct the Hebrew spelling and the report is recomputed.
Adding up the letters of the name ישב gives 312.
312
The number 312 is the Torah word ישב — «to sit, dwell» (Genesis 4:16).
Wherefore Levi hath no portion nor inheritance with his brethren; HaShem is his inheritance, according as HaShem thy G-d spoke unto him.--
This is from the portion Eikev. What it is about: “Because you will heed”: the land of seven fruits; the blessing after meals; manna as a test; the second paragraph of the Shema.
Other 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) — 312. A Torah word with the same number is ישב — “to sit, dwell” (Genesis 4:16).
Reduced, each letter to one digit (mispar katan) — 6. A Torah word with the same number is בד — “alone, apart” (Genesis 2:18).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 33. A Torah word with the same number is גל — “heap of stones” (Genesis 31:46).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1153.
Squares of the letter values (mispar perati) — 90104.
Building: the sum grows with each letter (mispar bone’eh) — 632. A Torah word with the same number is בכרתי — “my birthright” (Genesis 27:36).
The letters that come out are מבש — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 342. A Torah word with the same number is בשם — “spice, fragrance” (Exodus 25:6).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 792. A Torah word with the same number is תשבץ — “checkered work” (Exodus 28:4).

The name ישב appears in the Torah as a word 22 times. The first time is Genesis 4:16. Another 71 times it stands with prefixes — “and”, “in”, “the”.
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 ישב these are י and ב. The Pentateuch has 5 such verses. The first of them is Exodus 15:6:
ימינך ה׳ נאדרי בכח ימינך ה׳ תרעץ אויב
This is from the portion Beshalach. What it is about: The parting of the sea and the song of Moses and Miriam; manna and quail; water from the rock; the war with Amalek.
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.
