131813 ÷ 80 
We want to figure out the number of times 131813 can be divided by 80.

Let's proceed to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 80

Going ahead to step 2:
The number 80 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 80

On to step 3:
80 goes into 131 1 times with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 80 from 131, we get 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 80

Step 4:
The number 80 fits into 518 6 times, leaving a remainder of 38.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 480 from 518 leaves us with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 80

Let's proceed to step 5:
The number 80 fits into 381 4 times, leaving a remainder of 61.
The next digit of our result is 4. 
Result so far: 164.0
If we take 320 away from 381, we end up with 61.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 80

On to step 6:
613 divided by 80 is 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 1647.0
Subtract 560 from 613 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
If we divide 530 by 80, we get 6 and a remainder of 50.
The next digit of our result is 6. 
Result so far: 1647.6
Subtract 480 from 530 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
The number 80 fits into 500 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 1647.66
The remainder is 20 after subtracting 480 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 1647.66 with a balance of 0.02.
