We're dividing 559995 by 12 
The aim is to understand the frequency of 12 in 559995.

Going ahead to step 1:
5 divided by 12 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 12

Advancing to step 2:
12 can be fit into 55 4 times, resulting in a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 48 away from 55, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 12

Moving on to step 3:
The number 12 fits into 79 6 times, leaving a remainder of 7.
The next digit of our result is 6. 
Result so far: 46.0
If we subtract 72 from 79, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 12

Moving on to step 4:
When dividing 79 by 12, we get 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 466.0
Subtract 72 from 79 to get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 12

On to step 5:
12 goes into 79 6 times with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 4666.0
If we take 72 away from 79, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 12

Going ahead to step 6:
When dividing 75 by 12, we get 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 46666.0
Subtract 72 from 75 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 12, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 46666.2
The remainder is 6 after subtracting 24 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 46666.25
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.

On to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 46666.25
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.

Moving on to step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 46666.25
Subtract 0 from 0 to 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.

The final result is 46666.25 with a remainder of 0.0.
