Let's divide 829774 by 3
The aim is to understand the frequency of 3 in 829774.

Going ahead to step 1:
When dividing 8 by 3, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 2 after subtracting 6 from 8.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 3

On to step 2:
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: 27.0
Subtract 21 from 22 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

On to step 3:
3 can be fit into 19 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 276.0
If we take 18 away from 19, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 3

Going ahead to step 4:
3 goes into 17 5 times with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 2765.0
If we subtract 15 from 17, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 3

Advancing to step 5:
3 goes into 27 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 27659.0
Deduct 27 from 27 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Going ahead to step 6:
When dividing 4 by 3, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 276591.0
If we subtract 3 from 4, 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.

Moving on 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: 276591.3
Subtracting 9 from 10 leaves us 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.

Moving on to step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 276591.33
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.

Our division results in 276591.33 with a remaining 0.001.
