120937 ÷ 80 
Our goal is to divide 120937 by 80.

Step 1:
The number 80 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 80

Step 2:
The number 80 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 80

Moving on to step 3:
When dividing 120 by 80, we get 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 80 from 120 to get 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 80

On to step 4:
80 goes into 409 5 times with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 400 from 409 leaves us with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 80

Moving on to step 5:
80 can be fit into 93 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
Subtract 80 from 93 to get 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 80

Step 6:
When dividing 137 by 80, we get 1 with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1511.0
If we take 80 away from 137, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
The number 80 fits into 570 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 1511.7
If we subtract 560 from 570, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 80, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 1511.71
If we take 80 away from 100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 1511.712
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1511.7125
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1511.7125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1511.7125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1511.7125 with a remaining 0.0.
