We look at the division of 643179 by 7 
Let's see how many times 7 fits into 643179.

Advancing to step 1:
6 divided by 7 is 0 with 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 (4) from the dividend, add it to 6, then carry on: 64 / 7

Let's proceed to step 2:
7 goes into 64 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 1 after subtracting 63 from 64.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 7

Step 3:
7 goes into 13 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 7 from 13 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 7

Advancing to step 4:
7 goes into 61 8 times with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 918.0
Subtracting 56 from 61 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 7

Going ahead to step 5:
The number 7 fits into 57 8 times, leaving a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 9188.0
Deduct 56 from 57 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 7

Advancing to step 6:
7 can be fit into 19 2 times, resulting in a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 91882.0
Subtract 14 from 19 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.

Going ahead to step 7:
If we divide 50 by 7, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 91882.7
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.

Advancing to step 8:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 91882.71
Subtract 7 from 10 to 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.

On to step 9:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 91882.714
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.

Step 10:
If we divide 20 by 7, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 91882.7142
Subtracting 14 from 20 leaves us 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.

Let's proceed to step 11:
If we divide 60 by 7, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 91882.71428
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
7 goes into 40 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 91882.714285
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.

Step 13:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 91882.7142857
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.

Going ahead to step 14:
If we divide 10 by 7, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 91882.71428571
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.

Our division results in 91882.71428571 with a remaining 3e-09.
