We look at the division of 668594 by 7 
We want to divide 668594 by 7.

Advancing to step 1:
If we divide 6 by 7, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 7

Moving on to step 2:
7 can be fit into 66 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 63 away from 66, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 7

On to step 3:
7 goes into 38 5 times with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we subtract 35 from 38, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 7

Moving on to step 4:
When dividing 35 by 7, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 955.0
Subtracting 35 from 35 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 7

Step 5:
7 goes into 9 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 9551.0
Deduct 7 from 9 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 7

Going ahead to step 6:
When dividing 24 by 7, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 95513.0
If we subtract 21 from 24, 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.

Advancing to step 7:
When dividing 30 by 7, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 95513.4
Subtract 28 from 30 to 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.

Going ahead to step 8:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 95513.42
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.

Going ahead to step 9:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 95513.428
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.

Going ahead to step 10:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 95513.4285
If we subtract 35 from 40, we 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.

Advancing to step 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 95513.42857
If we take 49 away from 50, we end up 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.

Advancing to step 12:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 95513.428571
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.

Moving on to step 13:
When dividing 30 by 7, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 95513.4285714
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.

Moving on to step 14:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 95513.42857142
Subtract 14 from 20 to 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.

The final outcome is 95513.42857142, with a leftover of 6e-09.
