82829317 divided by 640 
Let's see how many times 640 fits into 82829317.

Step 1:
8 divided by 640 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 640

Let's proceed to step 2:
When dividing 82 by 640, we get 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 82 after subtracting 0 from 82.
Append the next digit (8) from the dividend to 82 and continue with: 828 / 640

Let's proceed to step 3:
640 goes into 828 1 times with a remainder of 188.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 640 from 828, we get 188.
Append the next digit (2) from the dividend to 188 and continue with: 1882 / 640

Let's proceed to step 4:
640 goes into 1882 2 times with a remainder of 602.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 602 after subtracting 1280 from 1882.
Include the next digit (9) from the dividend after 602, then repeat: 6029 / 640

Going ahead to step 5:
6029 divided by 640 is 9 with a remainder of 269.
The next digit of our result is 9. 
Result so far: 129.0
Subtract 5760 from 6029 to get 269.
Fetch the next digit (3) from the dividend, attach it to 269 and continue: 2693 / 640

Moving on to step 6:
2693 divided by 640 is 4 with a remainder of 133.
The next digit of our result is 4. 
Result so far: 1294.0
Subtract 2560 from 2693 to get 133.
Grab the next digit (1) from the dividend, add it to 133, then carry on: 1331 / 640

On to step 7:
1331 divided by 640 is 2 with a remainder of 51.
Use 2 as the next digit of our solution. 
Result so far: 12942.0
If we subtract 1280 from 1331, we get 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 640

On to step 8:
When dividing 517 by 640, we get 0 with a remainder of 517.
The number 0 becomes the next digit in our result. 
Result so far: 129420.0
If we subtract 0 from 517, we get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Step 9:
If we divide 5170 by 640, we get 8 and a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 129420.8
Deduct 5120 from 5170 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
500 divided by 640 is 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 129420.8
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 11:
5000 divided by 640 is 7 with a remainder of 520.
Record the quotient 7 as the next digit in the result. 
Result so far: 129420.807
The remainder is 520 after subtracting 4480 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 12:
When dividing 5200 by 640, we get 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 129420.8078
The remainder is 80 after subtracting 5120 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
If we divide 800 by 640, we get 1 and a remainder of 160.
Record the quotient 1 as the next digit in the result. 
Result so far: 129420.80781
If we subtract 640 from 800, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
If we divide 1600 by 640, we get 2 and a remainder of 320.
The next digit of our result is 2. 
Result so far: 129420.807812
If we take 1280 away from 1600, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 129420.8078125
If we take 3200 away from 3200, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 16:
When dividing 0 by 640, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 129420.8078125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 129420.8078125 with a balance of 0.0.
