Arrays cutoff in multicol - 2 columns

The Problem

Hey, I spent about 3 hours trying to solve this problem with multicol in LaTeX. Hope it would help some people out: arrays cuttoff in LaTeX

So as you could see, my arrays in the align* environment are cut off in the multicol environment that looked fine in the align* environment: Arrays in an align* environment

Here’s my code:

begin{align*}...end{align*} without cut off:

documentclass[11pt]{article}
usepackage{header}
usepackage{pgfplots}
allowdisplaybreaks
renewcommand{arraystretch}{1.5}

begin{document}

begin{align*} 
left[begin{array}{cccc|c} 
0 & 0 & 1 & -frac{5}{6} & -frac{35}{3} 
0 & 1 & 0 & 1 & 2 
0 & 1 & frac{9}{5} & 0 & frac{111}{5} 
1 & 0 & 0 & 0 & 19
end{array}right]  
text{$R_3-frac{9}{5}R_1$} 
left[begin{array}{cccc|c}

0 & 1 & 0 & 1 & 2 
0 & 1 & 0 & frac{3}{2} & frac{216}{5} 
1 & 0 & 0 & 0 & 19
end{array}right]  
text{$R_3-R_1$} 
left[begin{array}{cccc|c}

0 & 1 & 0 & 1 & 2

1 & 0 & 0 & 0 & 19
end{array}right]

end{array}right]  
end{align*}

multicol with the cut off:

The Solution

If your compiled LaTeX solution is to split up the long begin{align*}...end{align*} into a few`begin{align*}…end{align*}’ so you have something like:

begin{multicol}{2}
...
begin{align*}...end{align*}
begin{align*}...end{align*}
begin{align*}...end{align*}
...
end{multicol}

So, correct code:

begin{multicol*}{2}
begin{align*}
