We look at the division of 104572 by 3 
Let's see how many times 3 fits into 104572.

Advancing to step 1:
3 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

On to step 2:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 9 from 10, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Let's proceed to step 3:
3 can be fit into 14 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 34.0
Deduct 12 from 14 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 3

Moving on to step 4:
3 goes into 25 8 times with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 348.0
Subtracting 24 from 25 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

Step 5:
3 can be fit into 17 5 times, resulting in a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 3485.0
Deduct 15 from 17 and we're left with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

On to step 6:
3 can be fit into 22 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 34857.0
If we subtract 21 from 22, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 34857.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 34857.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 34857.33 with a balance of 0.001.
