12873 ÷ 10 
We're looking to find how many times 10 goes into 12873.

Let's proceed to step 1:
10 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 10

Step 2:
10 can be fit into 12 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 2 after subtracting 10 from 12.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 10

On to step 3:
The number 10 fits into 28 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 20 from 28 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 10

Moving on to step 4:
10 can be fit into 87 8 times, resulting in a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
If we subtract 80 from 87, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 10

On to step 5:
The number 10 fits into 73 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 1287.0
If we take 70 away from 73, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 6:
If we divide 30 by 10, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 1287.3
If we take 30 away from 30, 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.

Let's proceed to step 7:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1287.3
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1287.3
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.

Our division results in 1287.3 with a remaining 0.0.
