We look at the division of 669159 by 7 
We're looking to find how many times 7 goes into 669159.

On to step 1:
When dividing 6 by 7, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 7

Going ahead to step 2:
7 goes into 66 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 63 from 66 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 7

Moving on to step 3:
39 divided by 7 is 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 95.0
If we take 35 away from 39, we end up with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 7

Let's proceed to step 4:
The number 7 fits into 41 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 955.0
If we take 35 away from 41, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 7

Moving on to step 5:
The number 7 fits into 65 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 9559.0
Subtracting 63 from 65 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 7

Moving on to step 6:
The number 7 fits into 29 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 95594.0
Subtract 28 from 29 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.

Going ahead to step 7:
When dividing 10 by 7, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 95594.1
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.

Going ahead to step 8:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 95594.14
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.

Moving on to step 9:
7 goes into 20 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 95594.142
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 10:
When dividing 60 by 7, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 95594.1428
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 11:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 95594.14285
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.

Advancing to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 95594.142857
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.

On to step 13:
10 divided by 7 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 95594.1428571
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.

Let's proceed to step 14:
7 goes into 30 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 95594.14285714
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.

Our division results in 95594.14285714 with a remaining 2e-09.
