580209 divided by 7 
We're looking to find how many times 7 goes into 580209.

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
Subtract 0 from 5 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 7

On to step 2:
The number 7 fits into 58 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 56 away from 58, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 7

Advancing to step 3:
When dividing 20 by 7, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Subtract 14 from 20 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 7

On to step 4:
When dividing 62 by 7, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 828.0
The remainder is 6 after subtracting 56 from 62.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 7

Advancing to step 5:
If we divide 60 by 7, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 8288.0
The remainder is 4 after subtracting 56 from 60.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 7

Going ahead to step 6:
7 can be fit into 49 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 82887.0
If we subtract 49 from 49, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
7 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 82887.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 7, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 82887.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 82887.0 with a remainder of 0.0.
