We look at the division of 306473 by 12 
We're looking to find how many times 12 goes into 306473.

Moving on to step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 12

Step 2:
12 can be fit into 30 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 24 from 30 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 12

On to step 3:
66 divided by 12 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 60 from 66 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 12

Let's proceed to step 4:
The number 12 fits into 64 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 255.0
If we take 60 away from 64, we end up with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 12

On to step 5:
12 goes into 47 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 2553.0
If we take 36 away from 47, we end up with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 12

On to step 6:
If we divide 113 by 12, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 25539.0
If we take 108 away from 113, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
12 goes into 50 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 25539.4
Subtract 48 from 50 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 25539.41
Deduct 12 from 20 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 25539.416
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 12 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 25539.4166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 25539.4166 with a balance of 8e-05.
