Let's divide 307730 by 12
We want to divide 307730 by 12.

Advancing to step 1:
3 divided by 12 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 12

Let's proceed to step 2:
If we divide 30 by 12, we get 2 and 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.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 12

On to step 3:
When dividing 67 by 12, we get 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 60 from 67 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 12

Advancing to step 4:
If we divide 77 by 12, we get 6 and a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 256.0
If we take 72 away from 77, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 12

Step 5:
The number 12 fits into 53 4 times, leaving a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 2564.0
If we subtract 48 from 53, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 12

Advancing to step 6:
50 divided by 12 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 25644.0
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 25644.1
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.

Going ahead to step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 25644.16
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.

On to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 25644.166
Deduct 72 from 80 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.

The final outcome is 25644.166, with a leftover of 0.0008.
