We divide 543649 by 7
We want to figure out the number of times 543649 can be divided by 7.

Step 1:
7 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 7

Step 2:
If we divide 54 by 7, we get 7 and a remainder of 5.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 49 from 54 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 7

Let's proceed to step 3:
53 divided by 7 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtracting 49 from 53 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 7

Going ahead to step 4:
The number 7 fits into 46 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 776.0
The remainder is 4 after subtracting 42 from 46.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 7

Let's proceed to step 5:
44 divided by 7 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 7766.0
The remainder is 2 after subtracting 42 from 44.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 7

Moving on to step 6:
The number 7 fits into 29 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 77664.0
If we subtract 28 from 29, we 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 7:
If we divide 10 by 7, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 77664.1
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.

Step 8:
If we divide 30 by 7, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 77664.14
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.

Advancing to step 9:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 77664.142
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.

Step 10:
7 goes into 60 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 77664.1428
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:
If we divide 40 by 7, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 77664.14285
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 12:
When dividing 50 by 7, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 77664.142857
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.

Moving on to step 13:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 77664.1428571
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.

Going ahead to step 14:
30 divided by 7 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 77664.14285714
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.

In conclusion, the division gives 77664.14285714 with a balance of 2e-09.
