539038 divided by 12 
The aim is to understand the frequency of 12 in 539038.

Step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 12

Advancing to step 2:
12 goes into 53 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 48 from 53 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 12

Moving on to step 3:
12 can be fit into 59 4 times, resulting in a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we take 48 away from 59, we end up with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 12

Step 4:
12 goes into 110 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 449.0
Deduct 108 from 110 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 12

Step 5:
If we divide 23 by 12, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 4491.0
The remainder is 11 after subtracting 12 from 23.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 12

Advancing to step 6:
12 can be fit into 118 9 times, resulting in a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 44919.0
Subtract 108 from 118 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
12 goes into 100 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 44919.8
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 44919.83
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 44919.833
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 44919.833 with a balance of 0.0004.
