We look at the division of 657611 by 12 
The aim is to understand the frequency of 12 in 657611.

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
If we take 0 away from 6, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 12

Let's proceed to step 2:
When dividing 65 by 12, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 60 from 65 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 12

On to step 3:
12 can be fit into 57 4 times, resulting in a remainder of 9.
The next digit of our result is 4. 
Result so far: 54.0
Subtract 48 from 57 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 12

Going ahead to step 4:
The number 12 fits into 96 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 548.0
Subtract 96 from 96 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 12

Step 5:
1 divided by 12 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 5480.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 12

Step 6:
12 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 54800.0
If we subtract 0 from 11, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 12, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 54800.9
If we subtract 108 from 110, we get 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 8:
20 divided by 12 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 54800.91
The remainder is 8 after subtracting 12 from 20.
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 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 54800.916
Deduct 72 from 80 and we're left 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 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 54800.9166
Deduct 72 from 80 and we're left 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.

After the division, we end up with 54800.9166 and a remainder of 8e-05.
