We divide 646729 by 7
We want to divide 646729 by 7.

Going ahead 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
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 7

Let's proceed to step 2:
64 divided by 7 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 63 from 64 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 7

Step 3:
16 divided by 7 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Subtract 14 from 16 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 7

Going ahead to step 4:
27 divided by 7 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 923.0
Subtracting 21 from 27 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 7

Advancing to step 5:
62 divided by 7 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 9238.0
The remainder is 6 after subtracting 56 from 62.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 7

Step 6:
69 divided by 7 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 92389.0
If we take 63 away from 69, 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 7:
7 goes into 60 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 92389.8
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.

Let's proceed to step 8:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 92389.85
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.

Moving on to step 9:
7 goes into 50 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 92389.857
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.

On to step 10:
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: 92389.8571
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 11:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 92389.85714
Subtracting 28 from 30 leaves us 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.

On to step 12:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 92389.857142
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 13:
7 goes into 60 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 92389.8571428
Subtracting 56 from 60 leaves us 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.

On to step 14:
When dividing 40 by 7, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 92389.85714285
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.

In conclusion, the division gives 92389.85714285 with a balance of 5e-09.
