We look at the division of 307215 by 82 
Let's see how many times 82 fits into 307215.

Moving on to step 1:
If we divide 3 by 82, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 82

Moving on to step 2:
30 divided by 82 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 82

Going ahead to step 3:
If we divide 307 by 82, we get 3 and a remainder of 61.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 246 from 307 leaves us with 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 82

Step 4:
When dividing 612 by 82, we get 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtracting 574 from 612 leaves us with 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 82

Advancing to step 5:
381 divided by 82 is 4 with a remainder of 53.
The number 4 becomes the next digit in our result. 
Result so far: 374.0
If we take 328 away from 381, we end up with 53.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 82

Advancing to step 6:
82 goes into 535 6 times with a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 3746.0
Subtracting 492 from 535 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
When dividing 430 by 82, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 3746.5
Subtracting 410 from 430 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 82 fits into 200 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 3746.52
Subtract 164 from 200 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
If we divide 360 by 82, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 3746.524
Deduct 328 from 360 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
82 goes into 320 3 times with a remainder of 74.
Write down 3 as next digit of the result. 
Result so far: 3746.5243
Subtracting 246 from 320 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 11:
The number 82 fits into 740 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 3746.52439
Subtract 738 from 740 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
82 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3746.52439
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
When dividing 200 by 82, we get 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 3746.5243902
Subtract 164 from 200 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
82 can be fit into 360 4 times, resulting in a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 3746.52439024
Subtract 328 from 360 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 3746.52439024 and a remainder of 3.2e-08.
