503619 divided by 12 
Our goal is to divide 503619 by 12.

Moving on to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 12

Let's proceed to step 2:
12 can be fit into 50 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 2 after subtracting 48 from 50.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 12

Moving on to step 3:
12 goes into 23 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we take 12 away from 23, we end up with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 12

Let's proceed to step 4:
12 can be fit into 116 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 419.0
The remainder is 8 after subtracting 108 from 116.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 12

Let's proceed to step 5:
When dividing 81 by 12, we get 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 4196.0
Deduct 72 from 81 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 12

Advancing to step 6:
99 divided by 12 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 41968.0
Deduct 96 from 99 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 12, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 41968.2
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
60 divided by 12 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 41968.25
If we take 60 away from 60, we end up 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.

Moving on to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 41968.25
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.

Going ahead to step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 41968.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 41968.25, and the remainder is 0.0.
