278386 ÷ 31 
We want to divide 278386 by 31.

Advancing to step 1:
If we divide 2 by 31, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 31

Moving on to step 2:
When dividing 27 by 31, we get 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 31

Step 3:
31 can be fit into 278 8 times, resulting in a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 248 from 278 and we're left with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 31

On to step 4:
If we divide 303 by 31, we get 9 and a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Deduct 279 from 303 and we're left with 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 31

Step 5:
31 can be fit into 248 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 898.0
Subtract 248 from 248 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 31

Going ahead to step 6:
If we divide 6 by 31, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 8980.0
Subtracting 0 from 6 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
60 divided by 31 is 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 8980.1
The remainder is 29 after subtracting 31 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 8:
The number 31 fits into 290 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 8980.19
If we subtract 279 from 290, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
110 divided by 31 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 8980.193
If we subtract 93 from 110, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
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: 8980.1935
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.

Let's proceed to step 11:
When dividing 150 by 31, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 8980.19354
If we take 124 away from 150, we end up with 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 12:
The number 31 fits into 260 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 8980.193548
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
31 goes into 120 3 times with a remainder of 27.
The next digit of our result is 3. 
Result so far: 8980.1935483
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 14:
The number 31 fits into 270 8 times, leaving a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 8980.19354838
Subtracting 248 from 270 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 8980.19354838 with a remainder of 2.2e-08.
