51730 divided by 12 
We're looking to find how many times 12 goes into 51730.

On to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 12

Going ahead to step 2:
If we divide 51 by 12, we get 4 and a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 48 from 51 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 12

Advancing to step 3:
12 can be fit into 37 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 1 after subtracting 36 from 37.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 12

Advancing to step 4:
The number 12 fits into 13 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 431.0
The remainder is 1 after subtracting 12 from 13.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 12

Step 5:
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: 4310.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 6:
12 can be fit into 100 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 4310.8
Deduct 96 from 100 and we're left 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 7:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 4310.83
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.

Going ahead to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 4310.833
Subtracting 36 from 40 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.

After the division, we end up with 4310.833 and a remainder of 0.0004.
