We divide 571996 by 12
The aim is to understand the frequency of 12 in 571996.

Let's proceed to step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 12

Let's proceed to step 2:
12 goes into 57 4 times with a remainder of 9.
The next digit of our result is 4. 
Result so far: 4.0
If we take 48 away from 57, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 12

Going ahead to step 3:
12 can be fit into 91 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 47.0
The remainder is 7 after subtracting 84 from 91.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 12

Step 4:
The number 12 fits into 79 6 times, leaving a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 476.0
If we take 72 away from 79, we end up with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 12

Advancing to step 5:
79 divided by 12 is 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 4766.0
Subtract 72 from 79 to get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 12

Going ahead to step 6:
If we divide 76 by 12, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 47666.0
If we take 72 away from 76, 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:
If we divide 40 by 12, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 47666.3
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.

Moving on to step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 47666.33
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 47666.33 and a remainder of 0.004.
