We're dividing 19563474 by 12 
Let's see how many times 12 fits into 19563474.

Step 1:
12 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 12

Going ahead to step 2:
The number 12 fits into 19 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 12 from 19 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 12

Step 3:
75 divided by 12 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 72 from 75 and we're left with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 12

Let's proceed to step 4:
The number 12 fits into 36 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 163.0
The remainder is 0 after subtracting 36 from 36.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 12

Advancing to step 5:
12 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 1630.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 12

On to step 6:
If we divide 34 by 12, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 16302.0
If we take 24 away from 34, we end up with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 12

Moving on to step 7:
The number 12 fits into 107 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 163028.0
Deduct 96 from 107 and we're left with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 12

Step 8:
The number 12 fits into 114 9 times, leaving a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 1630289.0
The remainder is 6 after subtracting 108 from 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
60 divided by 12 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1630289.5
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1630289.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1630289.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 1630289.5 with a balance of 0.0.
