We divide 587480 by 12
The aim is to understand the frequency of 12 in 587480.

Advancing to step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 12

Advancing to step 2:
58 divided by 12 is 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 48 from 58 and we're left with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 12

Going ahead to step 3:
12 can be fit into 107 8 times, resulting in a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 96 from 107 leaves us with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 12

Moving on to step 4:
12 goes into 114 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 489.0
Deduct 108 from 114 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 12

Advancing to step 5:
When dividing 68 by 12, we get 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 4895.0
Deduct 60 from 68 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 12

Going ahead to step 6:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 48956.0
If we subtract 72 from 80, we get 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 7:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 48956.6
Deduct 72 from 80 and we're left 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.

Moving on to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 48956.66
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 48956.66 with a remainder of 0.008.
