Let's divide 864083 by 31
Our goal is to divide 864083 by 31.

Going ahead to step 1:
If we divide 8 by 31, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 31

Let's proceed to step 2:
31 goes into 86 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 62 from 86 leaves us with 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 31

Let's proceed to step 3:
If we divide 244 by 31, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtract 217 from 244 to get 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 31

Let's proceed to step 4:
If we divide 270 by 31, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 278.0
The remainder is 22 after subtracting 248 from 270.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 31

Moving on to step 5:
The number 31 fits into 228 7 times, leaving a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 2787.0
The remainder is 11 after subtracting 217 from 228.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 31

On to step 6:
When dividing 113 by 31, we get 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 27873.0
If we subtract 93 from 113, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
31 can be fit into 200 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 27873.6
The remainder is 14 after subtracting 186 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 31 fits into 140 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 27873.64
Deduct 124 from 140 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
31 goes into 160 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 27873.645
Subtracting 155 from 160 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
31 goes into 50 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 27873.6451
Subtracting 31 from 50 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
31 goes into 190 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 27873.64516
If we subtract 186 from 190, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
31 goes into 40 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 27873.645161
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
31 goes into 90 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 27873.6451612
Subtracting 62 from 90 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
The number 31 fits into 280 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 27873.64516129
Subtracting 279 from 280 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 27873.64516129 with a remainder of 1e-09.
