We're dividing 510088 by 12 
The aim is to understand the frequency of 12 in 510088.

Going ahead to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 12

On to step 2:
12 can be fit into 51 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 48 from 51 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 12

Let's proceed to step 3:
If we divide 30 by 12, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 42.0
The remainder is 6 after subtracting 24 from 30.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 12

Advancing to step 4:
When dividing 60 by 12, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 425.0
Subtracting 60 from 60 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 12

On to step 5:
8 divided by 12 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 4250.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 12

Moving on to step 6:
12 goes into 88 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 42507.0
If we take 84 away from 88, we end up 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.

Let's proceed to step 7:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 42507.3
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 8:
12 goes into 40 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 42507.33
Subtracting 36 from 40 leaves us 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.

The quotient of the division is 42507.33, and the remainder is 0.004.
