664612 divided by 7 
Let's see how many times 7 fits into 664612.

Advancing to step 1:
The number 7 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 7

Going ahead to step 2:
7 can be fit into 66 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 63 from 66 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 7

Moving on to step 3:
7 goes into 34 4 times with a remainder of 6.
The next digit of our result is 4. 
Result so far: 94.0
Subtract 28 from 34 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 7

Moving on to step 4:
The number 7 fits into 66 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 949.0
Deduct 63 from 66 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 7

Advancing to step 5:
When dividing 31 by 7, we get 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 9494.0
The remainder is 3 after subtracting 28 from 31.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 7

Moving on to step 6:
When dividing 32 by 7, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 94944.0
If we take 28 away from 32, 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.

Going ahead to step 7:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 94944.5
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.

On to step 8:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 94944.57
Deduct 49 from 50 and we're left 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.

Let's proceed to step 9:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 94944.571
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.

Moving on to step 10:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 94944.5714
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.

On to step 11:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 94944.57142
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.

Advancing to step 12:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 94944.571428
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 13:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 94944.5714285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 94944.57142857
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.

The final outcome is 94944.57142857, with a leftover of 1e-09.
