125540 divided by 80 
We want to figure out the number of times 125540 can be divided by 80.

Let's proceed to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 80

Let's proceed to step 2:
The number 80 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 80

Moving on to step 3:
When dividing 125 by 80, we get 1 with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 45 after subtracting 80 from 125.
Include the next digit (5) from the dividend after 45, then repeat: 455 / 80

Advancing to step 4:
The number 80 fits into 455 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 55 after subtracting 400 from 455.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 80

Advancing to step 5:
80 goes into 554 6 times with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 156.0
Subtracting 480 from 554 leaves us with 74.
Bring next digit (0) of the dividend behind the 74 and repeat the process: 740 / 80

Step 6:
When dividing 740 by 80, we get 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 1569.0
The remainder is 20 after subtracting 720 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
200 divided by 80 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 1569.2
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1569.25
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.

Going ahead to step 9:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1569.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 1569.25
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.

In conclusion, the division gives 1569.25 with a balance of 0.0.
