Let's divide 663121 by 83
We want to divide 663121 by 83.

Moving on to step 1:
83 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 83

On to step 2:
83 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 83

On to step 3:
663 divided by 83 is 7 with a remainder of 82.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 82 after subtracting 581 from 663.
Append the next digit (1) from the dividend to 82 and continue with: 821 / 83

Moving on to step 4:
83 goes into 821 9 times with a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Deduct 747 from 821 and we're left with 74.
Include the next digit (2) from the dividend after 74, then repeat: 742 / 83

Let's proceed to step 5:
The number 83 fits into 742 8 times, leaving a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 798.0
Subtracting 664 from 742 leaves us with 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 83

Let's proceed to step 6:
83 can be fit into 781 9 times, resulting in a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 7989.0
If we subtract 747 from 781, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
83 can be fit into 340 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 7989.4
If we take 332 away from 340, 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.

Going ahead to step 8:
If we divide 80 by 83, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 7989.4
Deduct 0 from 80 and we're left 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 9:
83 goes into 800 9 times with a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 7989.409
If we take 747 away from 800, we end up 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.

Let's proceed to step 10:
530 divided by 83 is 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 7989.4096
If we take 498 away from 530, we end up 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 11:
The number 83 fits into 320 3 times, leaving a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 7989.40963
If we take 249 away from 320, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
The number 83 fits into 710 8 times, leaving a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 7989.409638
If we subtract 664 from 710, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
83 goes into 460 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 7989.4096385
Subtract 415 from 460 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
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: 7989.40963855
The remainder is 35 after subtracting 415 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 7989.40963855 with a remaining 3.5e-08.
