We look at the division of 64921080 by 83 
We want to figure out the number of times 64921080 can be divided by 83.

Step 1:
6 divided by 83 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 83

Going ahead to step 2:
The number 83 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 83

Going ahead to step 3:
83 goes into 649 7 times with a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 581 from 649 to get 68.
Bring next digit (2) of the dividend behind the 68 and repeat the process: 682 / 83

Step 4:
682 divided by 83 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtracting 664 from 682 leaves us with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 83

Step 5:
If we divide 181 by 83, we get 2 and a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 782.0
The remainder is 15 after subtracting 166 from 181.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 83

On to step 6:
When dividing 150 by 83, we get 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 7821.0
Subtracting 83 from 150 leaves us with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 83

Going ahead to step 7:
678 divided by 83 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 78218.0
Deduct 664 from 678 and we're left with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 83

Step 8:
83 can be fit into 140 1 times, resulting in a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 782181.0
Deduct 83 from 140 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
The number 83 fits into 570 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 782181.6
The remainder is 72 after subtracting 498 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
The number 83 fits into 720 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 782181.68
Subtract 664 from 720 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
560 divided by 83 is 6 with a remainder of 62.
The next digit of our result is 6. 
Result so far: 782181.686
The remainder is 62 after subtracting 498 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 12:
83 can be fit into 620 7 times, resulting in a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 782181.6867
If we subtract 581 from 620, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 13:
If we divide 390 by 83, we get 4 and a remainder of 58.
The next digit of our result is 4. 
Result so far: 782181.68674
Subtract 332 from 390 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 14:
580 divided by 83 is 6 with a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 782181.686746
Deduct 498 from 580 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 15:
The number 83 fits into 820 9 times, leaving a remainder of 73.
Write down 9 as next digit of the result. 
Result so far: 782181.6867469
Deduct 747 from 820 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 16:
When dividing 730 by 83, we get 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 782181.68674698
The remainder is 66 after subtracting 664 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 782181.68674698 with a remaining 6.6e-08.
