We're dividing 336616 by 7 
The aim is to understand the frequency of 7 in 336616.

Step 1:
3 divided by 7 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 7

Going ahead to step 2:
33 divided by 7 is 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 28 from 33 and we're left with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 7

Let's proceed to step 3:
If we divide 56 by 7, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 56 from 56 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 7

Going ahead to step 4:
7 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 480.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 7

Advancing to step 5:
7 can be fit into 61 8 times, resulting in a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 4808.0
Subtract 56 from 61 to get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 7

On to step 6:
7 goes into 56 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 48088.0
If we take 56 away from 56, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 7 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 48088.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
7 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 48088.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 48088.0 with a balance of 0.0.
