Let's divide 643349 by 82
Let's see how many times 82 fits into 643349.

On to step 1:
If we divide 6 by 82, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 82

On to step 2:
82 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 82

Step 3:
When dividing 643 by 82, we get 7 with a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 69 after subtracting 574 from 643.
Take the next digit (3) from the dividend and append it to 69, then repeat: 693 / 82

On to step 4:
The number 82 fits into 693 8 times, leaving a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we take 656 away from 693, we end up with 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 82

Advancing to step 5:
The number 82 fits into 374 4 times, leaving a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 784.0
If we subtract 328 from 374, we get 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 82

Going ahead to step 6:
If we divide 469 by 82, we get 5 and a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 7845.0
Subtracting 410 from 469 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
590 divided by 82 is 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 7845.7
The remainder is 16 after subtracting 574 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
160 divided by 82 is 1 with a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 7845.71
The remainder is 78 after subtracting 82 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 9:
When dividing 780 by 82, we get 9 with a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 7845.719
The remainder is 42 after subtracting 738 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
The number 82 fits into 420 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 7845.7195
Subtracting 410 from 420 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
100 divided by 82 is 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 7845.71951
Deduct 82 from 100 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
If we divide 180 by 82, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 7845.719512
The remainder is 16 after subtracting 164 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
82 can be fit into 160 1 times, resulting in a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 7845.7195121
Subtract 82 from 160 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 14:
82 goes into 780 9 times with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 7845.71951219
Subtracting 738 from 780 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 7845.71951219, and the remainder is 4.2e-08.
