We look at the division of 502321 by 7 
Let's see how many times 7 fits into 502321.

Going ahead to step 1:
7 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 7

Advancing to step 2:
7 goes into 50 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 49 from 50 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 7

Let's proceed to step 3:
12 divided by 7 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtracting 7 from 12 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 7

Let's proceed to step 4:
53 divided by 7 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 717.0
Subtracting 49 from 53 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 7

Advancing to step 5:
When dividing 42 by 7, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 7176.0
The remainder is 0 after subtracting 42 from 42.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 7

Let's proceed to step 6:
7 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 71760.0
If we subtract 0 from 1, 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.

Moving on to step 7:
10 divided by 7 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 71760.1
If we subtract 7 from 10, we get 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 8:
If we divide 30 by 7, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 71760.14
The remainder is 2 after subtracting 28 from 30.
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 9:
If we divide 20 by 7, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 71760.142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 71760.1428
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
When dividing 40 by 7, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 71760.14285
Deduct 35 from 40 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
If we divide 50 by 7, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 71760.142857
If we subtract 49 from 50, 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 13:
When dividing 10 by 7, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 71760.1428571
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.

Moving on to step 14:
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: 71760.14285714
If we subtract 28 from 30, we 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.

In conclusion, the division gives 71760.14285714 with a balance of 2e-09.
