520009 ÷ 71 
We're looking to find how many times 71 goes into 520009.

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 take 0 away from 5, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 71

Going ahead to step 2:
If we divide 52 by 71, we get 0 and a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 71

Going ahead to step 3:
When dividing 520 by 71, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 497 from 520 to get 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 71

Step 4:
230 divided by 71 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Deduct 213 from 230 and we're left with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 71

Let's proceed to step 5:
When dividing 170 by 71, we get 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 732.0
If we take 142 away from 170, we end up with 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 71

Advancing to step 6:
The number 71 fits into 289 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 7324.0
Subtract 284 from 289 to 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.

Step 7:
If we divide 50 by 71, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 7324.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
The number 71 fits into 500 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 7324.07
The remainder is 3 after subtracting 497 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
The number 71 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 7324.07
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
300 divided by 71 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 7324.0704
Subtracting 284 from 300 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
71 goes into 160 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 7324.07042
If we take 142 away from 160, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
When dividing 180 by 71, we get 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 7324.070422
The remainder is 38 after subtracting 142 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 7324.070422, with a leftover of 3.8e-06.
