300385 ÷ 12 
We're looking to find how many times 12 goes into 300385.

Moving on to step 1:
12 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 12

Advancing to step 2:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 24 from 30 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 12

Advancing to step 3:
60 divided by 12 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 60 away from 60, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 12

Going ahead to step 4:
12 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 250.0
Subtract 0 from 3 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 12

Step 5:
When dividing 38 by 12, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 2503.0
Deduct 36 from 38 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 12

Step 6:
25 divided by 12 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 25032.0
If we subtract 24 from 25, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 25032.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 25032.08
If we subtract 96 from 100, we 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.

Let's proceed to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 25032.083
If we subtract 36 from 40, we 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.

Let's proceed to step 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 25032.0833
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.

In conclusion, the division gives 25032.0833 with a balance of 4e-05.
