You can use CSS grid to achieve this, this is the long-hand version for the purposes of illustration:

div.container {
    display: grid;
    grid-template-columns: 220px 20px auto;
    grid-template-rows: auto;
}

div.left {
    grid-column-start: 1;
    grid-column-end: 2;
    grid-row-start: row1-start
    grid-row-end: 3;
    background-color: Aqua;
}

div.right {
    grid-column-start: 3;
    grid-column-end: 4;
    grid-row-start: 1;
    grid-row-end; 1;
    background-color: Silver;
}

div.below {
    grid-column-start: 1;
    grid-column-end: 4;
    grid-row-start: 2;
    grid-row-end; 2;
}

Or the more traditional method using float and margin.

I have included a background colour in this example to help show where things are - and also what to do with content below the floated-area.

Don't put your styles inline in real life, extract them into a style sheet.

div.left {
    width: 200px;
    float: left;
    background-color: Aqua;
}

div.right {
    margin-left: 220px;
    background-color: Silver;
}

div.clear {
    clear: both;
}
