Let's divide 854873 by 3
We want to figure out the number of times 854873 can be divided by 3.

Step 1:
When dividing 8 by 3, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 6 from 8 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 3

Step 2:
When dividing 25 by 3, we get 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 24 from 25 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Going ahead to step 3:
14 divided by 3 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 284.0
Subtract 12 from 14 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

On to step 4:
The number 3 fits into 28 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 2849.0
Deduct 27 from 28 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Advancing to step 5:
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: 28495.0
The remainder is 2 after subtracting 15 from 17.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Let's proceed to step 6:
If we divide 23 by 3, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 284957.0
The remainder is 2 after subtracting 21 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 284957.6
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.

Going ahead to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 284957.66
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 284957.66 with a balance of 0.002.
