723444 divided by 12 
The aim is to understand the frequency of 12 in 723444.

Step 1:
If we divide 7 by 12, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 12

Advancing to step 2:
The number 12 fits into 72 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 72 from 72 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 12

Going ahead to step 3:
When dividing 3 by 12, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 12

Moving on to step 4:
12 goes into 34 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 602.0
Subtract 24 from 34 to get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 12

Let's proceed to step 5:
12 can be fit into 104 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 6028.0
Subtract 96 from 104 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 12

Step 6:
12 goes into 84 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 60287.0
Deduct 84 from 84 and we're left 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 7:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 60287.0
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.

Advancing to step 8:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 60287.0
If we take 0 away from 0, 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.

After the division, we end up with 60287.0 and a remainder of 0.0.
