We divide 431893 by 80
Our goal is to divide 431893 by 80.

Let's proceed to step 1:
80 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 80

On to step 2:
When dividing 43 by 80, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 80

On to step 3:
80 goes into 431 5 times with a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 400 away from 431, we end up with 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 80

Step 4:
The number 80 fits into 318 3 times, leaving a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtracting 240 from 318 leaves us with 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 80

Let's proceed to step 5:
When dividing 789 by 80, we get 9 with a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 539.0
Subtracting 720 from 789 leaves us with 69.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 80

Moving on to step 6:
693 divided by 80 is 8 with a remainder of 53.
Write down 8 as next digit of the result. 
Result so far: 5398.0
If we take 640 away from 693, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
80 can be fit into 530 6 times, resulting in a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 5398.6
Deduct 480 from 530 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
80 goes into 500 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 5398.66
Subtract 480 from 500 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 5398.66 with a remaining 0.02.
