Let's divide 575734 by 12
The aim is to understand the frequency of 12 in 575734.

Advancing to step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 12

Moving on to step 2:
The number 12 fits into 57 4 times, leaving a remainder of 9.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 48 from 57 leaves us with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 12

Step 3:
12 goes into 95 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtracting 84 from 95 leaves us with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 12

On to step 4:
If we divide 117 by 12, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 479.0
Subtracting 108 from 117 leaves us with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 12

Let's proceed to step 5:
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: 4797.0
The remainder is 9 after subtracting 84 from 93.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 12

Advancing to step 6:
If we divide 94 by 12, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 47977.0
Subtracting 84 from 94 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 47977.8
If we subtract 96 from 100, we get 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:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 47977.83
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.

Advancing to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 47977.833
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.

After the division, we end up with 47977.833 and a remainder of 0.0004.
