431574 ÷ 80 
Let's see how many times 80 fits into 431574.

Step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 80

Let's proceed to step 2:
43 divided by 80 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 80

Advancing to step 3:
When dividing 431 by 80, we get 5 with a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 400 from 431 leaves us with 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 80

Going ahead to step 4:
If we divide 315 by 80, we get 3 and a remainder of 75.
The next digit of our result is 3. 
Result so far: 53.0
The remainder is 75 after subtracting 240 from 315.
Fetch the next digit (7) from the dividend, attach it to 75 and continue: 757 / 80

Let's proceed to step 5:
If we divide 757 by 80, we get 9 and a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 539.0
The remainder is 37 after subtracting 720 from 757.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 80

Let's proceed to step 6:
If we divide 374 by 80, we get 4 and a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 5394.0
The remainder is 54 after subtracting 320 from 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
80 goes into 540 6 times with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 5394.6
Subtracting 480 from 540 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

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: 5394.67
The remainder is 40 after subtracting 560 from 600.
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:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5394.675
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.

Moving on to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5394.675
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.

On to step 11:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5394.675
Deduct 0 from 0 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.

Our division results in 5394.675 with a remaining 0.0.
