We divide 431814 by 80
Let's see how many times 80 fits into 431814.

Advancing to step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 80

Advancing to step 2:
The number 80 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 80

Step 3:
If we divide 431 by 80, we get 5 and a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 400 from 431 to get 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 80

Let's proceed to step 4:
80 can be fit into 318 3 times, resulting in a remainder of 78.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtract 240 from 318 to get 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 80

Moving on to step 5:
The number 80 fits into 781 9 times, leaving a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 539.0
If we take 720 away from 781, we end up with 61.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 80

Step 6:
80 goes into 614 7 times with a remainder of 54.
The next digit of our result is 7. 
Result so far: 5397.0
The remainder is 54 after subtracting 560 from 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
80 can be fit into 540 6 times, resulting in a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 5397.6
Subtract 480 from 540 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.

Going ahead to step 8:
80 goes into 600 7 times with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 5397.67
Subtract 560 from 600 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.

Let's proceed to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5397.675
Subtract 400 from 400 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.

On to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 5397.675
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.

Advancing to step 11:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5397.675
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.

The final outcome is 5397.675, with a leftover of 0.0.
