666396 divided by 83 
Our goal is to divide 666396 by 83.

Moving on to step 1:
When dividing 6 by 83, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 83

Moving on to step 2:
The number 83 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 83

On to step 3:
83 goes into 666 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 664 from 666 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 83

Let's proceed to step 4:
The number 83 fits into 23 0 times, leaving a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Deduct 0 from 23 and we're left with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 83

On to step 5:
The number 83 fits into 239 2 times, leaving a remainder of 73.
Use 2 as the next digit of our solution. 
Result so far: 802.0
Subtract 166 from 239 to get 73.
Fetch the next digit (6) from the dividend, attach it to 73 and continue: 736 / 83

Step 6:
736 divided by 83 is 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 8028.0
If we take 664 away from 736, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
The number 83 fits into 720 8 times, leaving a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 8028.8
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.

Let's proceed to step 8:
83 goes into 560 6 times with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 8028.86
If we take 498 away from 560, we end up with 62.
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 9:
83 can be fit into 620 7 times, resulting in a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 8028.867
If we take 581 away from 620, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
83 goes into 390 4 times with a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 8028.8674
Deduct 332 from 390 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
83 can be fit into 580 6 times, resulting in a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 8028.86746
Subtract 498 from 580 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 12:
83 can be fit into 820 9 times, resulting in a remainder of 73.
Put 9 as the next digit of the answer. 
Result so far: 8028.867469
Subtract 747 from 820 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 13:
83 goes into 730 8 times with a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 8028.8674698
Subtract 664 from 730 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 14:
83 can be fit into 660 7 times, resulting in a remainder of 79.
Record the quotient 7 as the next digit in the result. 
Result so far: 8028.86746987
Subtract 581 from 660 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The final outcome is 8028.86746987, with a leftover of 7.9e-08.
