We divide 806976 by 3
The aim is to understand the frequency of 3 in 806976.

On to step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Going ahead to step 2:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 18 away from 20, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Moving on to step 3:
If we divide 26 by 3, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 268.0
Subtract 24 from 26 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Step 4:
29 divided by 3 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 2689.0
Deduct 27 from 29 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 3

On to step 5:
27 divided by 3 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 26899.0
Subtract 27 from 27 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Let's proceed to step 6:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 268992.0
Deduct 6 from 6 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.

Moving on to step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 268992.0
If we take 0 away from 0, we end up 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.

Let's proceed to step 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 268992.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 268992.0, and the remainder is 0.0.
