864364 divided by 31 
We want to divide 864364 by 31.

Step 1:
When dividing 8 by 31, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 31

Advancing to step 2:
The number 31 fits into 86 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 62 from 86, we get 24.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 31

Step 3:
31 can be fit into 244 7 times, resulting in a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtract 217 from 244 to get 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 31

On to step 4:
The number 31 fits into 273 8 times, leaving a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 278.0
Deduct 248 from 273 and we're left with 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 31

On to step 5:
256 divided by 31 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 2788.0
Subtracting 248 from 256 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 31

Moving on to step 6:
31 goes into 84 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 27882.0
The remainder is 22 after subtracting 62 from 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
31 goes into 220 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 27882.7
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
If we divide 30 by 31, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 27882.7
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
31 can be fit into 300 9 times, resulting in a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 27882.709
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.

Advancing to step 10:
If we divide 210 by 31, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 27882.7096
If we subtract 186 from 210, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
31 can be fit into 240 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 27882.70967
If we subtract 217 from 240, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
230 divided by 31 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 27882.709677
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 27882.709677, with a leftover of 1.3e-06.
