125964 ÷ 80 
Let's see how many times 80 fits into 125964.

On to step 1:
80 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 80

On to step 2:
80 goes into 12 0 times with 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.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 80

Let's proceed to step 3:
125 divided by 80 is 1 with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 125 leaves us with 45.
Bring next digit (9) of the dividend behind the 45 and repeat the process: 459 / 80

Advancing to step 4:
459 divided by 80 is 5 with a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 400 from 459, we get 59.
Fetch the next digit (6) from the dividend, attach it to 59 and continue: 596 / 80

Let's proceed to step 5:
80 goes into 596 7 times with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
If we subtract 560 from 596, we get 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 80

Going ahead to step 6:
364 divided by 80 is 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 1574.0
Subtract 320 from 364 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
The number 80 fits into 440 5 times, leaving a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 1574.5
If we take 400 away from 440, we end up with 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:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1574.55
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1574.55 with a remainder of 0.0.
