873453 divided by 3 
Our goal is to divide 873453 by 3.

Moving on to step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 6 away from 8, we end up with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 3

Let's proceed to step 2:
When dividing 27 by 3, we get 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 27 away from 27, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

Going ahead to step 3:
3 goes into 3 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 291.0
Subtracting 3 from 3 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Moving on to step 4:
If we divide 4 by 3, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 2911.0
If we subtract 3 from 4, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

Let's proceed to step 5:
3 can be fit into 15 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 29115.0
If we take 15 away from 15, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

Advancing to step 6:
When dividing 3 by 3, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 291151.0
Deduct 3 from 3 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 291151.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 3 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 291151.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 291151.0 with a balance of 0.0.
