83076911 ÷ 640 
We want to divide 83076911 by 640.

Let's proceed to step 1:
8 divided by 640 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 640

Let's proceed to step 2:
83 divided by 640 is 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (0) from the dividend, attach it to 83 and continue: 830 / 640

Going ahead to step 3:
When dividing 830 by 640, we get 1 with a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 640 away from 830, we end up with 190.
Grab the next digit (7) from the dividend, add it to 190, then carry on: 1907 / 640

Let's proceed to step 4:
If we divide 1907 by 640, we get 2 and a remainder of 627.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1280 from 1907, we get 627.
Take the next digit (6) from the dividend and append it to 627, then repeat: 6276 / 640

Going ahead to step 5:
6276 divided by 640 is 9 with a remainder of 516.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Deduct 5760 from 6276 and we're left with 516.
Take the next digit (9) from the dividend and append it to 516, then repeat: 5169 / 640

Going ahead to step 6:
If we divide 5169 by 640, we get 8 and a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 1298.0
Subtract 5120 from 5169 to get 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 640

On to step 7:
If we divide 491 by 640, we get 0 and a remainder of 491.
Put 0 as the next digit of the answer. 
Result so far: 12980.0
Subtract 0 from 491 to get 491.
Bring next digit (1) of the dividend behind the 491 and repeat the process: 4911 / 640

On to step 8:
640 can be fit into 4911 7 times, resulting in a remainder of 431.
The next digit of our result is 7. 
Result so far: 129807.0
The remainder is 431 after subtracting 4480 from 4911.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Going ahead to step 9:
When dividing 4310 by 640, we get 6 with a remainder of 470.
Record the quotient 6 as the next digit in the result. 
Result so far: 129807.6
If we take 3840 away from 4310, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 10:
640 can be fit into 4700 7 times, resulting in a remainder of 220.
The number 7 becomes the next digit in our result. 
Result so far: 129807.67
If we subtract 4480 from 4700, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
2200 divided by 640 is 3 with a remainder of 280.
Put 3 as the next digit of the answer. 
Result so far: 129807.673
Subtract 1920 from 2200 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 12:
640 goes into 2800 4 times with a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 129807.6734
Deduct 2560 from 2800 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
The number 640 fits into 2400 3 times, leaving a remainder of 480.
Put 3 as the next digit of the answer. 
Result so far: 129807.67343
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.

Let's proceed to step 14:
4800 divided by 640 is 7 with a remainder of 320.
Use 7 as the next digit of our solution. 
Result so far: 129807.673437
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.

Step 15:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 129807.6734375
The remainder is 0 after subtracting 3200 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 129807.6734375
If we subtract 0 from 0, we 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.

Our division results in 129807.6734375 with a remaining 0.0.
