We look at the division of 795212 by 3 
The aim is to understand the frequency of 3 in 795212.

Moving on to step 1:
When dividing 7 by 3, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 6 from 7 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Moving on to step 2:
The number 3 fits into 19 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 18 from 19 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

On to step 3:
If we divide 15 by 3, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 265.0
Subtract 15 from 15 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 3

Advancing to step 4:
3 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 2650.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

Let's proceed to step 5:
3 goes into 21 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 26507.0
If we take 21 away from 21, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

Advancing to step 6:
If we divide 2 by 3, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 265070.0
Subtracting 0 from 2 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
3 goes into 20 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 265070.6
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 265070.66
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 265070.66 and a remainder of 0.002.
