We divide 648221 by 83
We want to figure out the number of times 648221 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
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 83

Step 2:
83 can be fit into 64 0 times, resulting in 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 (8) from the dividend and append it to 64, then repeat: 648 / 83

On to step 3:
If we divide 648 by 83, we get 7 and a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 581 from 648 and we're left with 67.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 83

Let's proceed to step 4:
The number 83 fits into 672 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtracting 664 from 672 leaves us with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 83

Advancing to step 5:
83 can be fit into 82 0 times, resulting in a remainder of 82.
The next digit of our result is 0. 
Result so far: 780.0
Subtract 0 from 82 to get 82.
Append the next digit (1) from the dividend to 82 and continue with: 821 / 83

Advancing to step 6:
83 can be fit into 821 9 times, resulting in a remainder of 74.
Put 9 as the next digit of the answer. 
Result so far: 7809.0
Subtract 747 from 821 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 7:
The number 83 fits into 740 8 times, leaving a remainder of 76.
The next digit of our result is 8. 
Result so far: 7809.8
If we subtract 664 from 740, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 8:
The number 83 fits into 760 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 7809.89
If we subtract 747 from 760, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
If we divide 130 by 83, we get 1 and a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 7809.891
Deduct 83 from 130 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
83 can be fit into 470 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 7809.8915
Deduct 415 from 470 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
When dividing 550 by 83, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 7809.89156
If we subtract 498 from 550, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
83 goes into 520 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 7809.891566
Subtract 498 from 520 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 7809.891566 with a remaining 2.2e-06.
