Let's divide 859007 by 3
The aim is to understand the frequency of 3 in 859007.

On to step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 6 from 8 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Step 2:
25 divided by 3 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 28.0
If we take 24 away from 25, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Step 3:
3 goes into 19 6 times with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 286.0
Subtract 18 from 19 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Going ahead to step 4:
When dividing 10 by 3, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 2863.0
If we take 9 away from 10, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Step 5:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 28633.0
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

Let's proceed to step 6:
3 can be fit into 17 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 286335.0
Subtract 15 from 17 to get 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:
20 divided by 3 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 286335.6
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 286335.66
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 286335.66, with a leftover of 0.002.
