We're dividing 305594 by 12 
We want to divide 305594 by 12.

Let's proceed to step 1:
12 goes into 3 0 times 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.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 12

On to step 2:
30 divided by 12 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 24 from 30 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 12

On to step 3:
When dividing 65 by 12, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 25.0
If we take 60 away from 65, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 12

Advancing to step 4:
The number 12 fits into 55 4 times, leaving a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 254.0
The remainder is 7 after subtracting 48 from 55.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 12

Moving on to step 5:
If we divide 79 by 12, we get 6 and a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 2546.0
Deduct 72 from 79 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 12

Step 6:
12 goes into 74 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 25466.0
The remainder is 2 after subtracting 72 from 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
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: 25466.1
Subtracting 12 from 20 leaves us 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.

Moving on to step 8:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 25466.16
Subtracting 72 from 80 leaves us 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:
When dividing 80 by 12, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 25466.166
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 25466.166 with a balance of 0.0008.
