We're dividing 858887 by 3 
The aim is to understand the frequency of 3 in 858887.

Step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 6 from 8 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

On to step 2:
The number 3 fits into 25 8 times, leaving a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 24 from 25, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Going ahead to step 3:
When dividing 18 by 3, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 286.0
If we take 18 away from 18, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

On to step 4:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2862.0
Subtract 6 from 8 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Advancing to step 5:
The number 3 fits into 28 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 28629.0
The remainder is 1 after subtracting 27 from 28.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

Step 6:
3 goes into 17 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 286295.0
Subtracting 15 from 17 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.

Step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 286295.6
Subtracting 18 from 20 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.

Let's proceed 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: 286295.66
Subtract 18 from 20 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.

In conclusion, the division gives 286295.66 with a balance of 0.002.
