We're dividing 536809 by 12 
The aim is to understand the frequency of 12 in 536809.

Step 1:
12 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 12

Let's proceed to step 2:
12 goes into 53 4 times with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 5 after subtracting 48 from 53.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 12

On to step 3:
If we divide 56 by 12, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 44.0
If we subtract 48 from 56, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 12

On to step 4:
12 goes into 88 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 447.0
If we subtract 84 from 88, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 12

On to step 5:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 4473.0
If we subtract 36 from 40, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 12

Going ahead to step 6:
12 can be fit into 49 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 44734.0
Subtracting 48 from 49 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 12, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 44734.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 44734.08
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 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 44734.083
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.

Moving on to step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 44734.0833
The remainder is 4 after subtracting 36 from 40.
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 44734.0833 with a balance of 4e-05.
