We're dividing 573985 by 12 
The aim is to understand the frequency of 12 in 573985.

Let's proceed 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
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 12

Going ahead to step 2:
12 can be fit into 57 4 times, resulting in a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 48 from 57 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 12

On to step 3:
The number 12 fits into 93 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtracting 84 from 93 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 12

Advancing to step 4:
The number 12 fits into 99 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 478.0
Deduct 96 from 99 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 12

Let's proceed to step 5:
12 goes into 38 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 4783.0
The remainder is 2 after subtracting 36 from 38.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 12

On to step 6:
If we divide 25 by 12, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 47832.0
Subtract 24 from 25 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 12 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 47832.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 47832.08
Subtracting 96 from 100 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.

Moving on to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 47832.083
If we take 36 away from 40, 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.

On to step 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 47832.0833
If we take 36 away from 40, 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.

The final result is 47832.0833 with a remainder of 4e-05.
