120559 divided by 80 
We're looking to find how many times 80 goes into 120559.

On to 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 subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 80

Advancing to step 2:
12 divided by 80 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 80

Moving on to step 3:
120 divided by 80 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 80 from 120, we get 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 80

On to step 4:
If we divide 405 by 80, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 400 away from 405, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 80

Moving on to step 5:
The number 80 fits into 55 0 times, leaving a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 80

Step 6:
The number 80 fits into 559 6 times, leaving a remainder of 79.
Put 6 as the next digit of the answer. 
Result so far: 1506.0
If we subtract 480 from 559, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 7:
80 goes into 790 9 times with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 1506.9
If we subtract 720 from 790, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 1506.98
Subtracting 640 from 700 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 1506.987
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1506.9875
Deduct 400 from 400 and we're left 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.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1506.9875
If we subtract 0 from 0, 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 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1506.9875
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.

The quotient of the division is 1506.9875, and the remainder is 0.0.
