We're dividing 588087 by 12 
The aim is to understand the frequency of 12 in 588087.

Let's proceed to step 1:
If we divide 5 by 12, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 12

On to step 2:
If we divide 58 by 12, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 48 from 58 and we're left with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 12

Moving on to step 3:
When dividing 108 by 12, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 108 from 108, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 12

Let's proceed to step 4:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 490.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 12

Let's proceed to step 5:
When dividing 8 by 12, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 4900.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 12

Going ahead to step 6:
If we divide 87 by 12, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 49007.0
The remainder is 3 after subtracting 84 from 87.
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:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 49007.2
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.

Going ahead to step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 49007.25
Subtracting 60 from 60 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 9:
0 divided by 12 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 49007.25
Deduct 0 from 0 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.

Step 10:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 49007.25
Deduct 0 from 0 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.

The final outcome is 49007.25, with a leftover of 0.0.
