We divide 663289 by 7
We want to figure out the number of times 663289 can be divided by 7.

Moving on to step 1:
6 divided by 7 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 7

On 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
Subtract 63 from 66 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 7

Advancing to step 3:
The number 7 fits into 33 4 times, leaving a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtract 28 from 33 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 7

Step 4:
When dividing 52 by 7, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 947.0
Subtracting 49 from 52 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 7

Going ahead to step 5:
7 can be fit into 38 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 9475.0
Subtract 35 from 38 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 7

On to step 6:
If we divide 39 by 7, we get 5 and a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 94755.0
If we take 35 away from 39, 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.

Let's proceed to step 7:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 94755.5
If we take 35 away from 40, we end up 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:
When dividing 50 by 7, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 94755.57
Subtract 49 from 50 to 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.

Advancing to step 9:
If we divide 10 by 7, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 94755.571
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.

On to step 10:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 94755.5714
If we subtract 28 from 30, we get 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 11:
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: 94755.57142
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 12:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 94755.571428
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.

Going ahead to step 13:
When dividing 40 by 7, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 94755.5714285
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 14:
7 goes into 50 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 94755.57142857
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.

The quotient of the division is 94755.57142857, and the remainder is 1e-09.
