We divide 840573 by 71
We're looking to find how many times 71 goes into 840573.

Moving on to step 1:
When dividing 8 by 71, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 71

Advancing to step 2:
71 goes into 84 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
If we take 71 away from 84, we end up with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 71

Let's proceed to step 3:
When dividing 130 by 71, we get 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 71 from 130 leaves us with 59.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 71

Moving on to step 4:
595 divided by 71 is 8 with a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Subtract 568 from 595 to get 27.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 71

Step 5:
The number 71 fits into 277 3 times, leaving a remainder of 64.
Record the quotient 3 as the next digit in the result. 
Result so far: 1183.0
Subtracting 213 from 277 leaves us with 64.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 71

On to step 6:
71 goes into 643 9 times with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 11839.0
The remainder is 4 after subtracting 639 from 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
The number 71 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11839.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
The number 71 fits into 400 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 11839.05
If we take 355 away from 400, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
If we divide 450 by 71, we get 6 and a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 11839.056
Subtracting 426 from 450 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
71 goes into 240 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 11839.0563
Subtract 213 from 240 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
The number 71 fits into 270 3 times, leaving a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 11839.05633
Subtract 213 from 270 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

After the division, we end up with 11839.05633 and a remainder of 5.7e-05.
