Use standard div_cell (#547)

# Objective

- Replace `num_integer::div_ceil` with the standard `div_ceil`.
- Closes #544

# Solution

[Rust 1.73.0 stabilized div_ceil for unsigned
integers.](https://blog.rust-lang.org/2023/10/05/Rust-1.73.0.html#stabilized-apis)

- Replaces `num_integer::div_ceil` with the standard `div_ceil`.
- Removes `num-integer` crate as a dependency because it is no longer
used.
