820726 ÷ 3 
The aim is to understand the frequency of 3 in 820726.

On to step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 3

Let's proceed to step 2:
22 divided by 3 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we take 21 away from 22, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

On to step 3:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 273.0
Deduct 9 from 10 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

Advancing to step 4:
If we divide 17 by 3, we get 5 and a remainder of 2.
The next digit of our result is 5. 
Result so far: 2735.0
Subtracting 15 from 17 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Going ahead to step 5:
If we divide 22 by 3, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 27357.0
If we subtract 21 from 22, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

Going ahead to step 6:
3 goes into 16 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 273575.0
Subtract 15 from 16 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.

Let's proceed to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 273575.3
Deduct 9 from 10 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.

Advancing to step 8:
3 goes into 10 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 273575.33
Deduct 9 from 10 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.

In conclusion, the division gives 273575.33 with a balance of 0.001.
