412555 divided by 80 
We want to divide 412555 by 80.

Going ahead to step 1:
4 divided by 80 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 80

Moving on to step 2:
80 goes into 41 0 times with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Include the next digit (2) from the dividend after 41, then repeat: 412 / 80

Step 3:
When dividing 412 by 80, we get 5 with a remainder of 12.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 400 from 412 to get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 80

Let's proceed to step 4:
80 goes into 125 1 times with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtracting 80 from 125 leaves us with 45.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 80

Going ahead to step 5:
80 goes into 455 5 times with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 515.0
The remainder is 55 after subtracting 400 from 455.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 80

Moving on to step 6:
The number 80 fits into 555 6 times, leaving a remainder of 75.
Write down 6 as next digit of the result. 
Result so far: 5156.0
The remainder is 75 after subtracting 480 from 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 7:
The number 80 fits into 750 9 times, leaving a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 5156.9
Deduct 720 from 750 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
80 goes into 300 3 times with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 5156.93
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
80 goes into 600 7 times with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 5156.937
Subtracting 560 from 600 leaves us 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 10:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5156.9375
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.

Let's proceed 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: 5156.9375
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:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5156.9375
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.

The quotient of the division is 5156.9375, and the remainder is 0.0.
