We're dividing 680648 by 5 
The aim is to understand the frequency of 5 in 680648.

Let's proceed to step 1:
5 can be fit into 6 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 5 from 6 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 5

Moving on to step 2:
If we divide 18 by 5, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 15 from 18 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 5

Going ahead to step 3:
When dividing 30 by 5, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 136.0
Subtracting 30 from 30 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 5

Moving on to step 4:
5 can be fit into 6 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1361.0
Subtracting 5 from 6 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 5

Advancing to step 5:
If we divide 14 by 5, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 13612.0
If we subtract 10 from 14, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 5

Going ahead to step 6:
The number 5 fits into 48 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 136129.0
Subtract 45 from 48 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 5, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 136129.6
Deduct 30 from 30 and we're left 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.

Advancing to step 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 136129.6
Subtracting 0 from 0 leaves us 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.

Step 9:
0 divided by 5 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 136129.6
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.

Our division results in 136129.6 with a remaining 0.0.
