82409095 ÷ 640 
Let's see how many times 640 fits into 82409095.

Advancing to step 1:
The number 640 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 640

Going ahead to step 2:
When dividing 82 by 640, we get 0 with a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Take the next digit (4) from the dividend and append it to 82, then repeat: 824 / 640

Going ahead to step 3:
If we divide 824 by 640, we get 1 and a remainder of 184.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 640 from 824, we get 184.
Grab the next digit (0) from the dividend, add it to 184, then carry on: 1840 / 640

On to step 4:
When dividing 1840 by 640, we get 2 with a remainder of 560.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 560 after subtracting 1280 from 1840.
Include the next digit (9) from the dividend after 560, then repeat: 5609 / 640

Step 5:
640 goes into 5609 8 times with a remainder of 489.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
If we take 5120 away from 5609, we end up with 489.
Take the next digit (0) from the dividend and append it to 489, then repeat: 4890 / 640

Moving on to step 6:
The number 640 fits into 4890 7 times, leaving a remainder of 410.
Record the quotient 7 as the next digit in the result. 
Result so far: 1287.0
If we take 4480 away from 4890, we end up with 410.
Take the next digit (9) from the dividend and append it to 410, then repeat: 4109 / 640

On to step 7:
640 can be fit into 4109 6 times, resulting in a remainder of 269.
Use 6 as the next digit of our solution. 
Result so far: 12876.0
Subtract 3840 from 4109 to get 269.
Bring next digit (5) of the dividend behind the 269 and repeat the process: 2695 / 640

Let's proceed to step 8:
The number 640 fits into 2695 4 times, leaving a remainder of 135.
Write down 4 as next digit of the result. 
Result so far: 128764.0
Subtracting 2560 from 2695 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 9:
If we divide 1350 by 640, we get 2 and a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 128764.2
The remainder is 70 after subtracting 1280 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
If we divide 700 by 640, we get 1 and a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 128764.21
Subtracting 640 from 700 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
640 goes into 600 0 times with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 128764.21
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 12:
If we divide 6000 by 640, we get 9 and a remainder of 240.
Use 9 as the next digit of our solution. 
Result so far: 128764.2109
Subtract 5760 from 6000 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
When dividing 2400 by 640, we get 3 with a remainder of 480.
Write down 3 as next digit of the result. 
Result so far: 128764.21093
Deduct 1920 from 2400 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
640 can be fit into 4800 7 times, resulting in a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 128764.210937
Subtract 4480 from 4800 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 128764.2109375
Subtract 3200 from 3200 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 16:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 128764.2109375
If we take 0 away from 0, 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.

The final result is 128764.2109375 with a remainder of 0.0.
