289500 divided by 12 
The aim is to understand the frequency of 12 in 289500.

Moving on to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 12

Step 2:
28 divided by 12 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 4 after subtracting 24 from 28.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 12

Advancing to step 3:
If we divide 49 by 12, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 24.0
Subtracting 48 from 49 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 12

Step 4:
When dividing 15 by 12, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 241.0
If we subtract 12 from 15, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 12

Let's proceed to step 5:
The number 12 fits into 30 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 2412.0
If we subtract 24 from 30, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 12

Let's proceed to step 6:
60 divided by 12 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 24125.0
Deduct 60 from 60 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.

Advancing to step 7:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24125.0
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.

Going ahead to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24125.0
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.

The final outcome is 24125.0, with a leftover of 0.0.
