We're dividing 640726 by 71 
Let's see how many times 71 fits into 640726.

Going ahead to step 1:
71 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 71

On to step 2:
When dividing 64 by 71, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 71

On to step 3:
When dividing 640 by 71, we get 9 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.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 71

On to step 4:
71 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 90.0
If we subtract 0 from 17, we get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 71

On to step 5:
71 goes into 172 2 times with a remainder of 30.
The next digit of our result is 2. 
Result so far: 902.0
If we subtract 142 from 172, we get 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 71

Going ahead to step 6:
The number 71 fits into 306 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 9024.0
If we take 284 away from 306, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
71 can be fit into 220 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 9024.3
If we subtract 213 from 220, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
70 divided by 71 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 9024.3
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
71 can be fit into 700 9 times, resulting in a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 9024.309
Subtract 639 from 700 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 10:
If we divide 610 by 71, we get 8 and a remainder of 42.
The next digit of our result is 8. 
Result so far: 9024.3098
Subtract 568 from 610 to get 42.
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 11:
The number 71 fits into 420 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 9024.30985
Deduct 355 from 420 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 12:
71 can be fit into 650 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 9024.309859
If we subtract 639 from 650, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
If we divide 110 by 71, we get 1 and a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 9024.3098591
Subtract 71 from 110 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 14:
The number 71 fits into 390 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 9024.30985915
Deduct 355 from 390 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 9024.30985915 and a remainder of 3.5e-08.
