502957 ÷ 3 
Our goal is to divide 502957 by 3.

On to step 1:
3 goes into 5 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 3 from 5 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Going ahead to step 2:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 18 from 20 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Going ahead to step 3:
3 goes into 22 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 167.0
Subtracting 21 from 22 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

Going ahead to step 4:
3 can be fit into 19 6 times, resulting in a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 1676.0
Subtract 18 from 19 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 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: 16765.0
If we take 15 away from 15, we end up with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 3

Step 6:
3 goes into 7 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 167652.0
Subtracting 6 from 7 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.

Advancing to step 7:
10 divided by 3 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 167652.3
If we subtract 9 from 10, we 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.

On to step 8:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 167652.33
If we subtract 9 from 10, we 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.

After the division, we end up with 167652.33 and a remainder of 0.001.
