We're dividing 538085 by 12 
The aim is to understand the frequency of 12 in 538085.

Step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 12

Moving on to step 2:
The number 12 fits into 53 4 times, leaving a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 48 from 53 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 12

Moving on to step 3:
When dividing 58 by 12, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtract 48 from 58 to get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 12

On to step 4:
If we divide 100 by 12, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 448.0
If we take 96 away from 100, we end up with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 12

On to step 5:
48 divided by 12 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4484.0
Deduct 48 from 48 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 12

Moving on to step 6:
If we divide 5 by 12, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 44840.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
12 can be fit into 50 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 44840.4
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 44840.41
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 12 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 44840.416
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 44840.4166
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 44840.4166 with a balance of 8e-05.
