We divide 87872321 by 3
We're looking to find how many times 3 goes into 87872321.

Going ahead to step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Let's proceed to step 2:
If we divide 27 by 3, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtract 27 from 27 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Step 3:
If we divide 8 by 3, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 292.0
If we subtract 6 from 8, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 3

Let's proceed to step 4:
27 divided by 3 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 2929.0
If we take 27 away from 27, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 3

Going ahead to step 5:
3 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 29290.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 3

Going ahead to step 6:
3 goes into 23 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 292907.0
The remainder is 2 after subtracting 21 from 23.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Let's proceed to step 7:
When dividing 22 by 3, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 2929077.0
Subtracting 21 from 22 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 3

On to step 8:
3 can be fit into 11 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 29290773.0
If we subtract 9 from 11, we 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.

On to step 9:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 29290773.6
If we take 18 away from 20, we end up 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.

Moving on to step 10:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 29290773.66
If we take 18 away from 20, we end up 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.

Our division results in 29290773.66 with a remaining 0.002.
