We divide 512720 by 7
We want to divide 512720 by 7.

Going ahead to step 1:
If we divide 5 by 7, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 7

Advancing to step 2:
The number 7 fits into 51 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 49 from 51, we get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 7

Step 3:
22 divided by 7 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 73.0
Subtract 21 from 22 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 7

Moving on to step 4:
7 goes into 17 2 times with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 732.0
Subtract 14 from 17 to get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 7

Step 5:
The number 7 fits into 32 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 7324.0
If we subtract 28 from 32, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 7

Advancing to step 6:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 73245.0
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.

Step 7:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 73245.7
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.

Step 8:
10 divided by 7 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 73245.71
If we take 7 away from 10, we end up 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.

Going ahead to step 9:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 73245.714
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.

On to step 10:
20 divided by 7 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 73245.7142
Deduct 14 from 20 and we're left 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.

Advancing to step 11:
If we divide 60 by 7, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 73245.71428
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.

Step 12:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 73245.714285
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.

Moving on to step 13:
50 divided by 7 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 73245.7142857
Subtracting 49 from 50 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.

Moving on to step 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 73245.71428571
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.

The final result is 73245.71428571 with a remainder of 3e-09.
