12215094 divided by 336 
Let's see how many times 336 fits into 12215094.

Let's proceed to step 1:
336 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 336

Let's proceed to step 2:
The number 336 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 336

Let's proceed to step 3:
122 divided by 336 is 0 with a remainder of 122.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 122 leaves us with 122.
Bring next digit (1) of the dividend behind the 122 and repeat the process: 1221 / 336

On to step 4:
336 can be fit into 1221 3 times, resulting in a remainder of 213.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 213 after subtracting 1008 from 1221.
Include the next digit (5) from the dividend after 213, then repeat: 2135 / 336

Moving on to step 5:
The number 336 fits into 2135 6 times, leaving a remainder of 119.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we take 2016 away from 2135, we end up with 119.
Take the next digit (0) from the dividend and append it to 119, then repeat: 1190 / 336

Moving on to step 6:
336 goes into 1190 3 times with a remainder of 182.
The next digit of our result is 3. 
Result so far: 363.0
If we subtract 1008 from 1190, we get 182.
Fetch the next digit (9) from the dividend, attach it to 182 and continue: 1829 / 336

Let's proceed to step 7:
336 can be fit into 1829 5 times, resulting in a remainder of 149.
The number 5 becomes the next digit in our result. 
Result so far: 3635.0
If we subtract 1680 from 1829, we get 149.
Take the next digit (4) from the dividend and append it to 149, then repeat: 1494 / 336

Step 8:
336 goes into 1494 4 times with a remainder of 150.
The number 4 becomes the next digit in our result. 
Result so far: 36354.0
The remainder is 150 after subtracting 1344 from 1494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 9:
336 can be fit into 1500 4 times, resulting in a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 36354.4
Subtracting 1344 from 1500 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 10:
When dividing 1560 by 336, we get 4 with a remainder of 216.
The number 4 becomes the next digit in our result. 
Result so far: 36354.44
Subtracting 1344 from 1560 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

In conclusion, the division gives 36354.44 with a balance of 0.216.
