In Gothic, numbers are represented using a combination of symbols for specific values. The Gothic numeral system is somewhat similar to the systems used in Latin and Greek, which involves using letters to represent values.

Here’s a breakdown of how to convert `678` into Gothic numerals:

1. Breakdown of the number:

- 70, which consists of 7 tens.
- 8, which is just 8.

2. Gothic numeral representations:
- The Gothic letter for 100 is "𐍈" (U), representing 100. Therefore, six hundreds would be represented as "𐍈𐍈𐍈𐍈𐍈𐍈".
- The Gothic letter for 10 is "𐍆" (F), representing 10. Thus, seven tens would be "𐍆𐍆𐍆𐍆𐍆𐍆𐍆".
- The Gothic numeral for 1 is "𐍀" (P). Therefore, eight would be represented as "𐍀𐍀𐍀𐍀𐍀𐍀𐍀𐍀".

3. Combining the symbols:
When we combine these symbols, we would have "𐍈𐍈𐍈𐍈𐍈𐍈𐍆𐍆𐍆𐍆𐍆𐍆𐍆𐍀𐍀𐍀𐍀𐍀𐍀𐍀𐍀".
