We divide 509343 by 7
Our goal is to divide 509343 by 7.

Advancing to step 1:
7 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 7

Advancing to step 2:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 49 away from 50, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 7

Advancing to step 3:
When dividing 19 by 7, we get 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Deduct 14 from 19 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 7

On to step 4:
The number 7 fits into 53 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 727.0
Deduct 49 from 53 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 7

Going ahead to step 5:
The number 7 fits into 44 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 7276.0
Deduct 42 from 44 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 7

Moving on to step 6:
If we divide 23 by 7, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 72763.0
Subtract 21 from 23 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.

On to step 7:
20 divided by 7 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 72763.2
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.

On to step 8:
If we divide 60 by 7, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 72763.28
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.

On to step 9:
When dividing 40 by 7, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 72763.285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
If we divide 50 by 7, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 72763.2857
Subtracting 49 from 50 leaves us 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.

Step 11:
When dividing 10 by 7, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 72763.28571
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.

On to step 12:
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: 72763.285714
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.

Step 13:
20 divided by 7 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 72763.2857142
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 14:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 72763.28571428
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.

The quotient of the division is 72763.28571428, and the remainder is 4e-09.
