We look at the division of 664715 by 7 
Let's see how many times 7 fits into 664715.

Moving on to step 1:
7 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 7

Advancing to step 2:
66 divided by 7 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 63 away from 66, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 7

Moving on to step 3:
When dividing 34 by 7, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Subtracting 28 from 34 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 7

Let's proceed to step 4:
67 divided by 7 is 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 949.0
Subtract 63 from 67 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 7

Let's proceed to step 5:
7 goes into 41 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 9495.0
Subtracting 35 from 41 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 7

Step 6:
7 can be fit into 65 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 94959.0
Deduct 63 from 65 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.

Advancing to step 7:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 94959.2
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.

On to step 8:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 94959.28
Subtracting 56 from 60 leaves us 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.

Moving on to step 9:
If we divide 40 by 7, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 94959.285
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 10:
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: 94959.2857
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.

Let's proceed to step 11:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 94959.28571
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.

Step 12:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 94959.285714
If we take 28 away from 30, we end up 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 13:
If we divide 20 by 7, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 94959.2857142
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.

Advancing to step 14:
When dividing 60 by 7, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 94959.28571428
If we take 56 away from 60, we end up 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.

The final result is 94959.28571428 with a remainder of 4e-09.
