We're dividing 579980 by 71 
We're looking to find how many times 71 goes into 579980.

On to step 1:
5 divided by 71 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 71

Step 2:
If we divide 57 by 71, we get 0 and a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 71

Let's proceed to step 3:
71 goes into 579 8 times with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 568 away from 579, we end up with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 71

Step 4:
119 divided by 71 is 1 with a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Deduct 71 from 119 and we're left with 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 71

Let's proceed to step 5:
488 divided by 71 is 6 with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 816.0
The remainder is 62 after subtracting 426 from 488.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 71

Let's proceed to step 6:
620 divided by 71 is 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 8168.0
Deduct 568 from 620 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 7:
520 divided by 71 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 8168.7
If we take 497 away from 520, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
230 divided by 71 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 8168.73
The remainder is 17 after subtracting 213 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
The number 71 fits into 170 2 times, leaving a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 8168.732
The remainder is 28 after subtracting 142 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
If we divide 280 by 71, we get 3 and a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 8168.7323
Subtract 213 from 280 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 11:
71 goes into 670 9 times with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 8168.73239
Subtract 639 from 670 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 12:
If we divide 310 by 71, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 8168.732394
Deduct 284 from 310 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
71 goes into 260 3 times with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 8168.7323943
Subtract 213 from 260 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 14:
The number 71 fits into 470 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 8168.73239436
If we take 426 away from 470, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 8168.73239436 with a remainder of 4.4e-08.
