We're dividing 806251 by 3 
We want to divide 806251 by 3.

Moving on to step 1:
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: 2.0
Deduct 6 from 8 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 3

Advancing to step 2:
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: 26.0
If we subtract 18 from 20, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

On to step 3:
3 goes into 26 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 268.0
Subtract 24 from 26 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

Moving on to step 4:
If we divide 22 by 3, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 2687.0
If we subtract 21 from 22, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

Moving on to step 5:
When dividing 15 by 3, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 26875.0
Subtracting 15 from 15 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Step 6:
If we divide 1 by 3, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 268750.0
Subtracting 0 from 1 leaves us 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.

On to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 268750.3
Subtract 9 from 10 to get 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:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 268750.33
Subtracting 9 from 10 leaves us 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.

The final result is 268750.33 with a remainder of 0.001.
