12684215 ÷ 308 
We're looking to find how many times 308 goes into 12684215.

Going ahead to step 1:
308 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 308

Advancing to step 2:
308 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 308

Let's proceed to step 3:
308 goes into 126 0 times with a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 126, we end up with 126.
Take the next digit (8) from the dividend and append it to 126, then repeat: 1268 / 308

Advancing to step 4:
308 goes into 1268 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 36 after subtracting 1232 from 1268.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 308

Step 5:
308 goes into 364 1 times with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 308 from 364 leaves us with 56.
Take the next digit (2) from the dividend and append it to 56, then repeat: 562 / 308

Advancing to step 6:
The number 308 fits into 562 1 times, leaving a remainder of 254.
Record the quotient 1 as the next digit in the result. 
Result so far: 411.0
The remainder is 254 after subtracting 308 from 562.
Bring next digit (1) of the dividend behind the 254 and repeat the process: 2541 / 308

Advancing to step 7:
When dividing 2541 by 308, we get 8 with a remainder of 77.
Use 8 as the next digit of our solution. 
Result so far: 4118.0
Subtract 2464 from 2541 to get 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 308

On to step 8:
When dividing 775 by 308, we get 2 with a remainder of 159.
The next digit of our result is 2. 
Result so far: 41182.0
The remainder is 159 after subtracting 616 from 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 9:
The number 308 fits into 1590 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 41182.5
If we take 1540 away from 1590, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
308 can be fit into 500 1 times, resulting in a remainder of 192.
Write down 1 as next digit of the result. 
Result so far: 41182.51
If we subtract 308 from 500, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 11:
When dividing 1920 by 308, we get 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 41182.516
The remainder is 72 after subtracting 1848 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
308 goes into 720 2 times with a remainder of 104.
The next digit of our result is 2. 
Result so far: 41182.5162
Subtract 616 from 720 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 13:
The number 308 fits into 1040 3 times, leaving a remainder of 116.
Record the quotient 3 as the next digit in the result. 
Result so far: 41182.51623
Subtract 924 from 1040 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 14:
If we divide 1160 by 308, we get 3 and a remainder of 236.
Record the quotient 3 as the next digit in the result. 
Result so far: 41182.516233
Deduct 924 from 1160 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final result is 41182.516233 with a remainder of 2.36e-05.
