803237 ÷ 3 
Our goal is to divide 803237 by 3.

Moving on to step 1:
When dividing 8 by 3, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 3

On to step 2:
When dividing 20 by 3, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 18 from 20 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

On to step 3:
3 goes into 23 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 267.0
Subtract 21 from 23 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

Step 4:
When dividing 22 by 3, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 2677.0
Subtracting 21 from 22 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 3

Let's proceed to step 5:
When dividing 13 by 3, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 26774.0
Subtract 12 from 13 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 3

Let's proceed to step 6:
When dividing 17 by 3, we get 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 267745.0
Deduct 15 from 17 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 267745.6
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
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: 267745.66
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 267745.66 and a remainder of 0.002.
