608840 ÷ 12 
The aim is to understand the frequency of 12 in 608840.

Step 1:
6 divided by 12 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 12

Let's proceed to step 2:
60 divided by 12 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 60 from 60 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 12

Going ahead to step 3:
When dividing 8 by 12, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 12

Advancing to step 4:
12 goes into 88 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 507.0
If we subtract 84 from 88, we get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 12

Step 5:
12 can be fit into 44 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 5073.0
Deduct 36 from 44 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 12

Let's proceed to step 6:
12 goes into 80 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 50736.0
Subtract 72 from 80 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.

Let's proceed to step 7:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 50736.6
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.

On to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 50736.66
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 50736.66 and a remainder of 0.008.
