We look at the division of 502904 by 7 
Let's see how many times 7 fits into 502904.

Moving on to step 1:
7 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 7

Step 2:
50 divided by 7 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 49 from 50 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 7

On to step 3:
The number 7 fits into 12 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Subtracting 7 from 12 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 7

Step 4:
59 divided by 7 is 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 718.0
The remainder is 3 after subtracting 56 from 59.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 7

Moving on to step 5:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 7184.0
Subtracting 28 from 30 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 7

On to step 6:
The number 7 fits into 24 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 71843.0
Deduct 21 from 24 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 71843.4
Deduct 28 from 30 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.

On to step 8:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 71843.42
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 71843.428
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
7 goes into 40 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 71843.4285
If we subtract 35 from 40, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
7 goes into 50 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 71843.42857
If we take 49 away from 50, we end up 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 12:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 71843.428571
Deduct 7 from 10 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
If we divide 30 by 7, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 71843.4285714
Subtracting 28 from 30 leaves us 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.

Step 14:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 71843.42857142
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 71843.42857142, with a leftover of 6e-09.
