262903 divided by 3 
We're looking to find how many times 3 goes into 262903.

Step 1:
The number 3 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 3

Moving on to step 2:
3 goes into 26 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 24 from 26 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

Going ahead to step 3:
The number 3 fits into 22 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we take 21 away from 22, we end up with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

Step 4:
If we divide 19 by 3, we get 6 and a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 876.0
The remainder is 1 after subtracting 18 from 19.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

On to step 5:
When dividing 10 by 3, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 8763.0
Subtract 9 from 10 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 3

Going ahead to step 6:
3 can be fit into 13 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 87634.0
Deduct 12 from 13 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 3 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 87634.3
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 87634.33
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 87634.33 with a balance of 0.001.
