We divide 640268 by 71
Let's see how many times 71 fits into 640268.

On to step 1:
If we divide 6 by 71, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 71

On to step 2:
71 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 71

Going ahead to step 3:
71 goes into 640 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 639 away from 640, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 71

Step 4:
71 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
Subtract 0 from 12 to get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 71

Step 5:
When dividing 126 by 71, we get 1 with a remainder of 55.
The next digit of our result is 1. 
Result so far: 901.0
If we take 71 away from 126, we end up with 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 71

On to step 6:
71 goes into 558 7 times with a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 9017.0
The remainder is 61 after subtracting 497 from 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
When dividing 610 by 71, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 9017.8
The remainder is 42 after subtracting 568 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
If we divide 420 by 71, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 9017.85
If we subtract 355 from 420, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
71 can be fit into 650 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 9017.859
If we take 639 away from 650, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
If we divide 110 by 71, we get 1 and a remainder of 39.
The next digit of our result is 1. 
Result so far: 9017.8591
If we take 71 away from 110, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 11:
71 can be fit into 390 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 9017.85915
If we subtract 355 from 390, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
When dividing 350 by 71, we get 4 with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 9017.859154
Subtract 284 from 350 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 13:
71 can be fit into 660 9 times, resulting in a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 9017.8591549
The remainder is 21 after subtracting 639 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
71 can be fit into 210 2 times, resulting in a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 9017.85915492
Deduct 142 from 210 and we're left 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.

The final outcome is 9017.85915492, with a leftover of 6.8e-08.
