We're dividing 312488 by 82 
We want to figure out the number of times 312488 can be divided by 82.

On to step 1:
82 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 82

On to step 2:
If we divide 31 by 82, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 82

Let's proceed to step 3:
The number 82 fits into 312 3 times, leaving a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 246 from 312 and we're left with 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 82

Let's proceed to step 4:
When dividing 664 by 82, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Deduct 656 from 664 and we're left with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 82

Step 5:
82 goes into 88 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 381.0
If we subtract 82 from 88, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 82

Let's proceed to step 6:
82 goes into 68 0 times with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 3810.0
If we subtract 0 from 68, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 7:
The number 82 fits into 680 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 3810.8
Deduct 656 from 680 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
When dividing 240 by 82, we get 2 with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 3810.82
The remainder is 76 after subtracting 164 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
82 can be fit into 760 9 times, resulting in a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 3810.829
Subtracting 738 from 760 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.

Let's proceed to step 10:
The number 82 fits into 220 2 times, leaving a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 3810.8292
The remainder is 56 after subtracting 164 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
82 can be fit into 560 6 times, resulting in a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 3810.82926
If we subtract 492 from 560, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
When dividing 680 by 82, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 3810.829268
If we subtract 656 from 680, 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 13:
The number 82 fits into 240 2 times, leaving a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 3810.8292682
If we subtract 164 from 240, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
82 goes into 760 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 3810.82926829
If we take 738 away from 760, we end up 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 3810.82926829 with a remainder of 2.2e-08.
