Something like this:

```elixir
iex> x = <<170, 192, 65, 0, 100, 0, 61, 86, 56, 171>>
iex> << _ :: bytes-4, onehundred :: bytes-1, _ :: bytes-1, sixtyone :: bytes-1, _rest :: binary >> = x          
<<170, 192, 65, 0, 100, 0, 61, 86, 56, 171>>
iex> onehundred
"d"
iex> sixtyone
"="

```

This assumes you want the fields as binaries. If you want them as integers:

```elixir
iex> << _ :: bytes-4, onehundred :: size(8), _ :: bytes-1, sixtyone :: size(8), _rest :: binary >> = x
<<170, 192, 65, 0, 100, 0, 61, 86, 56, 171>>
iex> sixtyone
61
iex> onehundred
100

```
