431480 divided by 80 
Our goal is to divide 431480 by 80.

Let's proceed to step 1:
80 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 80

Going ahead to step 2:
If we divide 43 by 80, we get 0 and a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 80

Let's proceed to step 3:
80 goes into 431 5 times with a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 31 after subtracting 400 from 431.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 80

On to step 4:
If we divide 314 by 80, we get 3 and a remainder of 74.
The next digit of our result is 3. 
Result so far: 53.0
The remainder is 74 after subtracting 240 from 314.
Include the next digit (8) from the dividend after 74, then repeat: 748 / 80

Step 5:
When dividing 748 by 80, we get 9 with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 539.0
Deduct 720 from 748 and we're left with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 80

On to step 6:
The number 80 fits into 280 3 times, leaving a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 5393.0
Subtract 240 from 280 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.

Going ahead to step 7:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5393.5
If we take 400 away from 400, we end up 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.

Let's proceed to step 8:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5393.5
If we take 0 away from 0, we end up 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 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5393.5
If we take 0 away from 0, we end up 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.

Our division results in 5393.5 with a remaining 0.0.
