We look at the division of 10489215 by 3 
We're looking to find how many times 3 goes into 10489215.

Advancing to step 1:
3 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
If we subtract 0 from 1, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Step 2:
3 goes into 10 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 9 away from 10, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

Advancing to step 3:
14 divided by 3 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we subtract 12 from 14, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Advancing to step 4:
When dividing 28 by 3, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 349.0
The remainder is 1 after subtracting 27 from 28.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 3

Advancing to step 5:
3 goes into 19 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 3496.0
If we subtract 18 from 19, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Let's proceed to step 6:
3 goes into 12 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 34964.0
Subtract 12 from 12 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Moving on to step 7:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 349640.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Going ahead to step 8:
If we divide 15 by 3, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3496405.0
Subtracting 15 from 15 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.

Going ahead to step 9:
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: 3496405.0
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.

Advancing to step 10:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3496405.0
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.

In conclusion, the division gives 3496405.0 with a balance of 0.0.
