We're dividing 172281 by 3 
Our goal is to divide 172281 by 3.

Step 1:
3 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

Moving on to step 2:
If we divide 17 by 3, we get 5 and a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 15 away from 17, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 3

Step 3:
If we divide 22 by 3, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 57.0
The remainder is 1 after subtracting 21 from 22.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

Let's proceed to step 4:
3 can be fit into 12 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 574.0
The remainder is 0 after subtracting 12 from 12.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

On to step 5:
3 goes into 8 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 5742.0
If we take 6 away from 8, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Moving on to step 6:
The number 3 fits into 21 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 57427.0
Subtracting 21 from 21 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.

Step 7:
0 divided by 3 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 57427.0
The remainder is 0 after subtracting 0 from 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 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 57427.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 57427.0, with a leftover of 0.0.
