We divide 559809 by 7
We want to figure out the number of times 559809 can be divided by 7.

Going ahead to step 1:
7 can be fit into 5 0 times, resulting in 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 (5) from the dividend to 5 and continue with: 55 / 7

Step 2:
7 can be fit into 55 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 49 from 55 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 7

Moving on to step 3:
69 divided by 7 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 79.0
The remainder is 6 after subtracting 63 from 69.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 7

Advancing to step 4:
7 goes into 68 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 799.0
Deduct 63 from 68 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 7

Let's proceed to step 5:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7997.0
If we subtract 49 from 50, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 7

Advancing to step 6:
7 goes into 19 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 79972.0
If we subtract 14 from 19, 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.

Step 7:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 79972.7
The remainder is 1 after subtracting 49 from 50.
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 8:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 79972.71
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 79972.714
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.

Let's proceed to step 10:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 79972.7142
If we subtract 14 from 20, we get 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 11:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 79972.71428
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
If we divide 40 by 7, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 79972.714285
Subtract 35 from 40 to 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.

Moving on to step 13:
7 goes into 50 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 79972.7142857
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.

Step 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 79972.71428571
Subtracting 7 from 10 leaves us 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.

The final outcome is 79972.71428571, with a leftover of 3e-09.
