We're dividing 456674 by 12 
The aim is to understand the frequency of 12 in 456674.

Going ahead to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 12

Step 2:
If we divide 45 by 12, we get 3 and a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 9 after subtracting 36 from 45.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 12

Step 3:
96 divided by 12 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we subtract 96 from 96, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 12

Step 4:
If we divide 6 by 12, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 380.0
If we take 0 away from 6, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 12

On to step 5:
67 divided by 12 is 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 3805.0
If we take 60 away from 67, we end up with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 12

On to step 6:
12 can be fit into 74 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 38056.0
Deduct 72 from 74 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
12 goes into 20 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 38056.1
If we subtract 12 from 20, 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.

Let's proceed to step 8:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 38056.16
If we take 72 away from 80, we end up 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 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 38056.166
Subtracting 72 from 80 leaves us 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.

In conclusion, the division gives 38056.166 with a balance of 0.0008.
