We're dividing 431183 by 80 
Our goal is to divide 431183 by 80.

Going ahead to step 1:
When dividing 4 by 80, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 80

Moving on to step 2:
80 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
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:
431 divided by 80 is 5 with a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 400 from 431 and we're left with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 80

On to step 4:
80 goes into 311 3 times with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
The remainder is 71 after subtracting 240 from 311.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 80

On to step 5:
When dividing 718 by 80, we get 8 with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 538.0
The remainder is 78 after subtracting 640 from 718.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 80

On to step 6:
When dividing 783 by 80, we get 9 with a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 5389.0
Deduct 720 from 783 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
80 goes into 630 7 times with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 5389.7
Subtract 560 from 630 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
If we divide 700 by 80, we get 8 and a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 5389.78
If we subtract 640 from 700, we 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.

Advancing to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 5389.787
If we subtract 560 from 600, we 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 10:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5389.7875
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 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5389.7875
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.

Going ahead to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 5389.7875
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.

After the division, we end up with 5389.7875 and a remainder of 0.0.
