305811 ÷ 3 
We want to divide 305811 by 3.

Step 1:
When dividing 3 by 3, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 3 from 3, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Advancing to step 2:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Moving on to step 3:
If we divide 5 by 3, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtracting 3 from 5 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

Going ahead to step 4:
3 goes into 28 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1019.0
If we subtract 27 from 28, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 3

On to step 5:
3 can be fit into 11 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 10193.0
Deduct 9 from 11 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

Going ahead to step 6:
3 goes into 21 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 101937.0
If we take 21 away from 21, we end up 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:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 101937.0
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.

Step 8:
3 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 101937.0
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 101937.0, with a leftover of 0.0.
