Let's divide 333948 by 12
The aim is to understand the frequency of 12 in 333948.

Advancing to step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 12

Going ahead to step 2:
12 goes into 33 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 24 from 33 to get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 12

On to step 3:
The number 12 fits into 93 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 84 from 93 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 12

Let's proceed to step 4:
99 divided by 12 is 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 278.0
If we subtract 96 from 99, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 12

Advancing to step 5:
34 divided by 12 is 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 2782.0
The remainder is 10 after subtracting 24 from 34.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 12

Let's proceed to step 6:
When dividing 108 by 12, we get 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 27829.0
If we subtract 108 from 108, we 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.

Let's proceed to step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 27829.0
Deduct 0 from 0 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.

Step 8:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 27829.0
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 27829.0 and a remainder of 0.0.
