How to split symbolic output string into multiple lines?

I am using the Symbolic Toolbox to solve a simple ODE that yields the following very long one-liner equation: 25*exp(-alpha*t) + exp(-alpha*t)*(400*heaviside(t - 5)*exp(alpha*t) - 25*heaviside(t) + 2000*heaviside(t - 10)*exp(alpha*t) - 2400*heaviside(t - 12)*exp(alpha*t) - 400*heaviside(t - 5)*exp(5*alpha) - 2000*heaviside(t - 10)*exp(10*alpha) + 2400*heaviside(t - 12)*exp(12*alpha) + 25*exp(alpha*t)*heaviside(t) + (80*heaviside(t))/alpha + (80*exp(alpha*t)*heaviside(t)*(alpha*t - 1))/alpha - (80*heaviside(t - 5)*exp(alpha*t)*(alpha*t - 1))/alpha - (200*heaviside(t - 10)*exp(alpha*t)*(alpha*t - 1))/alpha + (200*heaviside(t - 12)*exp(alpha*t)*(alpha*t - 1))/alpha + (80*heaviside(t - 5)*exp(5*alpha)*(5*alpha - 1))/alpha + (200*heaviside(t - 10)*exp(10*alpha)*(10*alpha - 1))/alpha - (200*heaviside(t - 12)*exp(12*alpha)*(12*alpha - 1))/alpha)

I would like to first split the equation into multiple lines, as shown above. (In the command window, the same equation appears in one long line).

Then I'd like to convert the multi-line output to Tex or Latex for insertion into a Word document (with MathType).
