We divide 350229 by 12
We're looking to find how many times 12 goes into 350229.

Let's proceed to step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 12

Let's proceed to step 2:
When dividing 35 by 12, we get 2 with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 24 away from 35, we end up with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 12

Advancing to step 3:
12 goes into 110 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 29.0
The remainder is 2 after subtracting 108 from 110.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 12

Step 4:
When dividing 22 by 12, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 291.0
If we subtract 12 from 22, we get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 12

Let's proceed to step 5:
The number 12 fits into 102 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 2918.0
Subtract 96 from 102 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 12

On to step 6:
The number 12 fits into 69 5 times, leaving a remainder of 9.
The next digit of our result is 5. 
Result so far: 29185.0
Subtracting 60 from 69 leaves us 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.

Moving on to step 7:
90 divided by 12 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 29185.7
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
60 divided by 12 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 29185.75
Subtracting 60 from 60 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 29185.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 29185.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 29185.75 with a balance of 0.0.
