665661 ÷ 83 
Let's see how many times 83 fits into 665661.

Moving on to step 1:
If we divide 6 by 83, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 83

On to step 2:
66 divided by 83 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 83

Step 3:
When dividing 665 by 83, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 664 away from 665, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 83

Step 4:
When dividing 16 by 83, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 80.0
If we take 0 away from 16, we end up with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 83

Going ahead to step 5:
When dividing 166 by 83, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 802.0
The remainder is 0 after subtracting 166 from 166.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 83

Going ahead to step 6:
The number 83 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 8020.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 83 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 8020.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 83 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 8020.01
The remainder is 17 after subtracting 83 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
When dividing 170 by 83, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 8020.012
Subtract 166 from 170 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
If we divide 40 by 83, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8020.012
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
If we divide 400 by 83, we get 4 and a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 8020.01204
Subtract 332 from 400 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 12:
83 can be fit into 680 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8020.012048
If we take 664 away from 680, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
83 can be fit into 160 1 times, resulting in a remainder of 77.
The next digit of our result is 1. 
Result so far: 8020.0120481
Deduct 83 from 160 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 14:
When dividing 770 by 83, we get 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 8020.01204819
Subtract 747 from 770 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 8020.01204819, with a leftover of 2.3e-08.
