We're dividing 721284 by 12 
We're looking to find how many times 12 goes into 721284.

Step 1:
7 divided by 12 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 12

Let's proceed to step 2:
72 divided by 12 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 72 from 72, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 12

Let's proceed to step 3:
The number 12 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 12

Step 4:
The number 12 fits into 12 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 601.0
Deduct 12 from 12 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 12

Moving on to step 5:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 6010.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 12

Step 6:
The number 12 fits into 84 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 60107.0
The remainder is 0 after subtracting 84 from 84.
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 7:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 60107.0
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 8:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 60107.0
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.

After the division, we end up with 60107.0 and a remainder of 0.0.
