812312 divided by 31 
We're looking to find how many times 31 goes into 812312.

Advancing to step 1:
8 divided by 31 is 0 with 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.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 31

On to step 2:
The number 31 fits into 81 2 times, leaving a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 62 from 81, we get 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 31

Advancing to step 3:
When dividing 192 by 31, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtract 186 from 192 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 31

Going ahead to step 4:
31 goes into 63 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 262.0
Deduct 62 from 63 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 31

Step 5:
When dividing 11 by 31, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 2620.0
If we take 0 away from 11, we end up with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 31

Going ahead to step 6:
The number 31 fits into 112 3 times, leaving a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 26203.0
If we subtract 93 from 112, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
The number 31 fits into 190 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 26203.6
The remainder is 4 after subtracting 186 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
31 goes into 40 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 26203.61
Deduct 31 from 40 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
31 can be fit into 90 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 26203.612
Deduct 62 from 90 and we're left 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 10:
31 goes into 280 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 26203.6129
If we take 279 away from 280, we end up 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.

On to step 11:
10 divided by 31 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 26203.6129
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 31, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 26203.612903
If we take 93 away from 100, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
31 can be fit into 70 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 26203.6129032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
The number 31 fits into 80 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 26203.61290322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 26203.61290322 with a remainder of 1.8e-08.
