We're dividing 640509 by 82 
We want to divide 640509 by 82.

Going ahead to step 1:
If we divide 6 by 82, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 82

Let's proceed to step 2:
When dividing 64 by 82, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 82

Step 3:
If we divide 640 by 82, we get 7 and a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 574 from 640, we get 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 82

Going ahead to step 4:
If we divide 665 by 82, we get 8 and a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtracting 656 from 665 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 82

Let's proceed to step 5:
When dividing 90 by 82, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 781.0
Deduct 82 from 90 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 82

On to step 6:
When dividing 89 by 82, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 7811.0
The remainder is 7 after subtracting 82 from 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
82 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 7811.0
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 8:
700 divided by 82 is 8 with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 7811.08
Subtract 656 from 700 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
If we divide 440 by 82, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 7811.085
If we take 410 away from 440, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
When dividing 300 by 82, we get 3 with a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 7811.0853
If we take 246 away from 300, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
82 can be fit into 540 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 7811.08536
If we subtract 492 from 540, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
The number 82 fits into 480 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 7811.085365
Subtract 410 from 480 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
The number 82 fits into 700 8 times, leaving a remainder of 44.
The next digit of our result is 8. 
Result so far: 7811.0853658
If we take 656 away from 700, 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.

Moving on to step 14:
82 can be fit into 440 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 7811.08536585
Deduct 410 from 440 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 7811.08536585 and a remainder of 3e-08.
