299419 ÷ 12 
Let's see how many times 12 fits into 299419.

On to step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 12

On to step 2:
When dividing 29 by 12, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 24 from 29, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 12

Moving on to step 3:
12 goes into 59 4 times with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 48 from 59 and we're left with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 12

Let's proceed to step 4:
114 divided by 12 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 249.0
Deduct 108 from 114 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 12

On to step 5:
61 divided by 12 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 2495.0
Subtract 60 from 61 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 12

Advancing to step 6:
When dividing 19 by 12, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 24951.0
Subtract 12 from 19 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 24951.5
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 12 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 24951.58
Subtracting 96 from 100 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 12 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 24951.583
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 24951.5833
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 24951.5833 with a remaining 4e-05.
