Now that I fixed the register on my Monroe LN-160x, the overflow bell works which means I can perform division. Here I am calculating 145 / 12 = 12 remainder 1. The quotient is at the top in red, the remainder is underneath it in black.
Just like multiplication is repeated addition, division is repeated subtraction. First you put the dividend (145) in the accumulator, then zero out the top row which will contain the quotient.
Next you enter the divisor (12) and set the repeat button. Then you move the carriage to right until it points to the leftmost column still greater than the divisor. 14 is greater than 12 so I move the carriage one position to the right to point to the tens place.
Now we turn the handle counterclockwise to subtract the divisor until we overflow and hear a bell. Then we turn the handle clockwise until we hear the bell again telling us we undid the overflow. We have our answer for the tens place.
Next we move the carriage one position to the left to point to the ones column and subtract until we overflow and hear the bell again, crank the handle clockwise until we undo the overflow and hear the bell, and we have our answer: 12 with a remainder of 1.
