We're dividing 278800 by 31 
We want to divide 278800 by 31.

Step 1:
If we divide 2 by 31, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 31

Advancing to step 2:
The number 31 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 31

Going ahead to step 3:
31 goes into 278 8 times with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 248 from 278 leaves us with 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 31

Let's proceed to step 4:
31 can be fit into 308 9 times, resulting in a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we subtract 279 from 308, we get 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 31

Going ahead to step 5:
If we divide 290 by 31, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 899.0
Subtracting 279 from 290 leaves us with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 31

On to step 6:
31 can be fit into 110 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 8993.0
If we take 93 away from 110, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
31 can be fit into 170 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 8993.5
If we subtract 155 from 170, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
31 can be fit into 150 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 8993.54
Subtract 124 from 150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
260 divided by 31 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 8993.548
Deduct 248 from 260 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
31 goes into 120 3 times with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 8993.5483
The remainder is 27 after subtracting 93 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 11:
31 goes into 270 8 times with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 8993.54838
If we subtract 248 from 270, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
31 goes into 220 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 8993.548387
If we subtract 217 from 220, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
When dividing 30 by 31, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 8993.548387
Subtract 0 from 30 to 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 14:
31 can be fit into 300 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 8993.54838709
If we take 279 away from 300, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 8993.54838709 and a remainder of 2.1e-08.
