Center divs and content inside a main div - html

Question

I am trying to achieve the following:
The text inside the square (example text: "1/4") should be centered horizontally
and vertically.
The four squares should be spread with the same
distance over the main container (red).
The text (example text: "Name", "Longer Name" etc.) should be centered over the squares, and not affect the spreading of the squares (point 2)
What I got this far is the code below. I would greatly appreciate if somebody could point me in the correct direction!
.container {
background-color: red;
width: 320px;
height: 320px;
margin: 30px auto 30px auto;
}
.inner {
display: flex;
}
.inner-content {
display: block;
/* width: 25%;*/
margin-left: auto;
margin-right: auto;
background-color: green;
}
.text {
width: 25%;
text-align: center;
}
.square {
margin-top: 5px;
height: 25px;
width: 25px;
vertical-align: top;
text-align: center;
color: #fff;
font-size: 14px;
font-weight: bold;
text-align: center;
background-color: black;
box-shadow: 0 0 0 2px red, 0 0 0 5px black;
}
<div class="container">
<div class="inner">
<div class="inner-content">
<span class="text">Name</span>
<div class="square">
1/4
</div>
</div>
<div class="inner-content">
<span class="text">Longer Name</span>
<div class="square">
1/4
</div>
</div>
<div class="inner-content">
<span class="text">Name</span>
<div class="square">
1/4
</div>
</div>
<div class="inner-content">

<div class="square">

</div>
</div>

Answer 1

Take a look at the following example:
* {
box-sizing: border-box;
}
.container {
background-color: red;
width: 320px;
height: 320px;
margin: 30px auto 30px auto;
padding: 5px;
}
.inner {
display: grid;
grid-template-columns: repeat(4, 1fr); /* fix spreading */
grid-column-gap: 5px;
}
.inner-content {
background-color: green;
text-align: center;
}
.text {
width: 100%;
}
.square {
margin: 5px auto; /* fix box centering */
height: 25px;
width: 25px;
vertical-align: top;
text-align: center;
color: #fff;
font-size: 14px;
font-weight: bold;
background-color: black;
box-shadow: 0 0 0 2px red, 0 0 0 5px black;
line-height: 25px; /* fix vertical center */
}
<div class="container">
<div class="inner">
<div class="inner-content">
<span class="text">Name</span>
<div class="square">
1/4
</div>
</div>
<div class="inner-content">
<span class="text">Longer Name</span>
<div class="square">
1/4
</div>
</div>
<div class="inner-content">
<span class="text">Name</span>
<div class="square">
1/4
</div>
</div>
<div class="inner-content">
<span class="text">Yo</span>
<div class="square">
1/4
</div>
</div>
</div>
