We divide 519622 by 12
We're looking to find how many times 12 goes into 519622.

Advancing to step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 12

Moving on to step 2:
When dividing 51 by 12, we get 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
If we take 48 away from 51, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 12

Going ahead to step 3:
The number 12 fits into 39 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtract 36 from 39 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 12

Advancing to step 4:
12 can be fit into 36 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 433.0
The remainder is 0 after subtracting 36 from 36.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 12

Step 5:
When dividing 2 by 12, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 4330.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 12

Step 6:
The number 12 fits into 22 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 43301.0
Deduct 12 from 22 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 43301.8
If we take 96 away from 100, 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:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 43301.83
Deduct 36 from 40 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.

Let's proceed to step 9:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 43301.833
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.

The final result is 43301.833 with a remainder of 0.0004.
