648814 ÷ 3 
The aim is to understand the frequency of 3 in 648814.

Step 1:
When dividing 6 by 3, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 6 from 6, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

Advancing to step 2:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 3 from 4 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

Step 3:
The number 3 fits into 18 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 216.0
If we subtract 18 from 18, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Advancing to step 4:
3 goes into 8 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2162.0
Subtract 6 from 8 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Moving on to step 5:
21 divided by 3 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 21627.0
If we take 21 away from 21, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

Advancing to step 6:
3 can be fit into 4 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 216271.0
Deduct 3 from 4 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 216271.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 216271.33
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 216271.33 with a balance of 0.001.
