We're dividing 31274547 by 80 
We want to divide 31274547 by 80.

Step 1:
The number 80 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 80

Advancing to step 2:
If we divide 31 by 80, we get 0 and a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 80

Moving on to step 3:
80 can be fit into 312 3 times, resulting in a remainder of 72.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 240 from 312 leaves us with 72.
Fetch the next digit (7) from the dividend, attach it to 72 and continue: 727 / 80

Step 4:
When dividing 727 by 80, we get 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtracting 720 from 727 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 80

On to step 5:
80 goes into 74 0 times with a remainder of 74.
The next digit of our result is 0. 
Result so far: 390.0
If we take 0 away from 74, we end up with 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 80

Let's proceed to step 6:
The number 80 fits into 745 9 times, leaving a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 3909.0
The remainder is 25 after subtracting 720 from 745.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 80

On to step 7:
When dividing 254 by 80, we get 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 39093.0
Deduct 240 from 254 and we're left with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 80

Step 8:
The number 80 fits into 147 1 times, leaving a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 390931.0
If we take 80 away from 147, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
670 divided by 80 is 8 with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 390931.8
If we subtract 640 from 670, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
300 divided by 80 is 3 with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 390931.83
Subtract 240 from 300 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.

Advancing to step 11:
If we divide 600 by 80, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 390931.837
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 390931.8375
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.

Moving on to step 13:
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: 390931.8375
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.

Let's proceed to step 14:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 390931.8375
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.

The final outcome is 390931.8375, with a leftover of 0.0.
