We look at the division of 872573 by 3 
We're looking to find how many times 3 goes into 872573.

Advancing to step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 6 away from 8, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Advancing to step 2:
The number 3 fits into 27 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 27 from 27, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

Let's proceed to step 3:
When dividing 2 by 3, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 290.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 3

Advancing to step 4:
3 goes into 25 8 times with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 2908.0
Subtract 24 from 25 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

Advancing to step 5:
The number 3 fits into 17 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 29085.0
Deduct 15 from 17 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 3

Moving on to step 6:
3 goes into 23 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 290857.0
Subtract 21 from 23 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.

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: 290857.6
Deduct 18 from 20 and we're left 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:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 290857.66
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.

In conclusion, the division gives 290857.66 with a balance of 0.002.
