We're dividing 639311 by 7 
Let's see how many times 7 fits into 639311.

Step 1:
If we divide 6 by 7, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 7

Going ahead to step 2:
If we divide 63 by 7, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 63 away from 63, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 7

On to step 3:
7 goes into 9 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Deduct 7 from 9 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 7

Advancing to step 4:
23 divided by 7 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 913.0
Subtract 21 from 23 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 7

Going ahead to step 5:
7 can be fit into 21 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 9133.0
Deduct 21 from 21 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 7

Let's proceed to step 6:
7 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 91330.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 91330.1
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.

Let's proceed to step 8:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 91330.14
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.

Advancing to step 9:
When dividing 20 by 7, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 91330.142
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.

Let's proceed to step 10:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 91330.1428
If we subtract 56 from 60, we 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 11:
7 goes into 40 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 91330.14285
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.

On to step 12:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 91330.142857
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.

Moving on to step 13:
If we divide 10 by 7, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 91330.1428571
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.

Let's proceed to step 14:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 91330.14285714
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.

In conclusion, the division gives 91330.14285714 with a balance of 2e-09.
