We look at the division of 644549 by 71 
We want to divide 644549 by 71.

Advancing 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
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 71

Advancing to step 2:
64 divided by 71 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 71

Let's proceed to step 3:
71 can be fit into 644 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 639 from 644, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 71

Moving on to step 4:
55 divided by 71 is 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 90.0
The remainder is 55 after subtracting 0 from 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 71

Going ahead to step 5:
If we divide 554 by 71, we get 7 and a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 907.0
The remainder is 57 after subtracting 497 from 554.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 71

Going ahead to step 6:
71 goes into 579 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 9078.0
The remainder is 11 after subtracting 568 from 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
110 divided by 71 is 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 9078.1
Subtracting 71 from 110 leaves us 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.

Let's proceed to step 8:
71 goes into 390 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 9078.15
Subtracting 355 from 390 leaves us 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.

Step 9:
71 goes into 350 4 times with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 9078.154
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.

Going ahead to step 10:
The number 71 fits into 660 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 9078.1549
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 11:
210 divided by 71 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 9078.15492
The remainder is 68 after subtracting 142 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 12:
680 divided by 71 is 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 9078.154929
If we take 639 away from 680, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 13:
The number 71 fits into 410 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 9078.1549295
Deduct 355 from 410 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 14:
71 can be fit into 550 7 times, resulting in a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 9078.15492957
Subtracting 497 from 550 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The quotient of the division is 9078.15492957, and the remainder is 5.3e-08.
