Let's divide 425348 by 12
The aim is to understand the frequency of 12 in 425348.

Step 1:
12 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 12

Let's proceed to step 2:
If we divide 42 by 12, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 36 from 42 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 12

Advancing to step 3:
65 divided by 12 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we subtract 60 from 65, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 12

Going ahead to step 4:
53 divided by 12 is 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 354.0
Subtracting 48 from 53 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 12

Let's proceed to step 5:
The number 12 fits into 54 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 3544.0
If we take 48 away from 54, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 12

Moving on to step 6:
If we divide 68 by 12, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 35445.0
Subtract 60 from 68 to 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.

On to 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: 35445.6
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.

Going ahead to step 8:
12 goes into 80 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 35445.66
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.

After the division, we end up with 35445.66 and a remainder of 0.008.
