640768 divided by 83 
Let's see how many times 83 fits into 640768.

Advancing to step 1:
83 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 83

Advancing to step 2:
83 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 83

Step 3:
83 can be fit into 640 7 times, resulting in a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 581 from 640 to get 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 83

On to step 4:
83 can be fit into 597 7 times, resulting in a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 77.0
The remainder is 16 after subtracting 581 from 597.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 83

Advancing to step 5:
83 can be fit into 166 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 772.0
The remainder is 0 after subtracting 166 from 166.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 83

Step 6:
When dividing 8 by 83, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 7720.0
If we take 0 away from 8, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
83 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 7720.0
If we take 0 away from 80, we end up with 80.
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 8:
83 goes into 800 9 times with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 7720.09
Subtracting 747 from 800 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.

Step 9:
83 goes into 530 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 7720.096
Subtracting 498 from 530 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
If we divide 320 by 83, we get 3 and a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 7720.0963
Subtract 249 from 320 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 11:
710 divided by 83 is 8 with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 7720.09638
If we take 664 away from 710, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
83 can be fit into 460 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 7720.096385
Deduct 415 from 460 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 13:
If we divide 450 by 83, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 7720.0963855
If we take 415 away from 450, we end up 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.

The final result is 7720.0963855 with a remainder of 3.5e-07.
