We're dividing 786898 by 12 
The aim is to understand the frequency of 12 in 786898.

Moving on to step 1:
12 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 12

Moving on to step 2:
12 goes into 78 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 72 from 78 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 12

Moving on to step 3:
If we divide 66 by 12, we get 5 and a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
If we subtract 60 from 66, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 12

On to step 4:
12 can be fit into 68 5 times, resulting in a remainder of 8.
The next digit of our result is 5. 
Result so far: 655.0
If we subtract 60 from 68, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 12

Step 5:
If we divide 89 by 12, we get 7 and a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 6557.0
The remainder is 5 after subtracting 84 from 89.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 12

Let's proceed to step 6:
12 goes into 58 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 65574.0
The remainder is 10 after subtracting 48 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 65574.8
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 65574.83
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.

Step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 65574.833
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.

The final outcome is 65574.833, with a leftover of 0.0004.
