509491 ÷ 71 
We want to figure out the number of times 509491 can be divided by 71.

Advancing to step 1:
When dividing 5 by 71, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 71

Step 2:
71 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 71

Step 3:
When dividing 509 by 71, we get 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 497 from 509 and we're left with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 71

Step 4:
71 goes into 124 1 times with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Subtract 71 from 124 to get 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 71

Going ahead to step 5:
71 can be fit into 539 7 times, resulting in a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 717.0
If we subtract 497 from 539, we get 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 71

Let's proceed to step 6:
71 can be fit into 421 5 times, resulting in a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 7175.0
Deduct 355 from 421 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
660 divided by 71 is 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 7175.9
If we subtract 639 from 660, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
210 divided by 71 is 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 7175.92
If we take 142 away from 210, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
71 can be fit into 680 9 times, resulting in a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 7175.929
Deduct 639 from 680 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
71 can be fit into 410 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 7175.9295
If we subtract 355 from 410, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 11:
71 can be fit into 550 7 times, resulting in a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 7175.92957
If we take 497 away from 550, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 12:
71 goes into 530 7 times with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 7175.929577
The remainder is 33 after subtracting 497 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final result is 7175.929577 with a remainder of 3.3e-06.
