We divide 905103 by 3
We want to figure out the number of times 905103 can be divided by 3.

Step 1:
3 can be fit into 9 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 9 from 9 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Advancing to step 2:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 3

Moving on to step 3:
3 can be fit into 5 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 301.0
If we subtract 3 from 5, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

Step 4:
21 divided by 3 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 3017.0
If we take 21 away from 21, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Step 5:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30170.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 3

Going ahead to step 6:
3 divided by 3 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 301701.0
Subtracting 3 from 3 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.

Let's proceed to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 301701.0
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.

Advancing to step 8:
3 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 301701.0
If we subtract 0 from 0, we 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.

The final result is 301701.0 with a remainder of 0.0.
