We're dividing 648925 by 12 
The aim is to understand the frequency of 12 in 648925.

Moving on to step 1:
6 divided by 12 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 12

On to step 2:
12 goes into 64 5 times with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 4 after subtracting 60 from 64.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 12

Let's proceed to step 3:
48 divided by 12 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we take 48 away from 48, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 12

Advancing to step 4:
When dividing 9 by 12, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 540.0
If we take 0 away from 9, we end up with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 12

On to step 5:
92 divided by 12 is 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 5407.0
Subtracting 84 from 92 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 12

Let's proceed to step 6:
12 can be fit into 85 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 54077.0
Deduct 84 from 85 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 12 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 54077.0
Subtract 0 from 10 to get 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 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 54077.08
If we take 96 away from 100, 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 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 54077.083
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.

Moving on to step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 54077.0833
If we subtract 36 from 40, 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.

The final outcome is 54077.0833, with a leftover of 4e-05.
