642925 ÷ 82 
Let's see how many times 82 fits into 642925.

Let's proceed to step 1:
6 divided by 82 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 82

Let's proceed to step 2:
82 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 82

Let's proceed to step 3:
If we divide 642 by 82, we get 7 and a remainder of 68.
The next digit of our result is 7. 
Result so far: 7.0
If we take 574 away from 642, we end up with 68.
Include the next digit (9) from the dividend after 68, then repeat: 689 / 82

On to step 4:
The number 82 fits into 689 8 times, leaving a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtracting 656 from 689 leaves us with 33.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 82

Moving on to step 5:
If we divide 332 by 82, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 784.0
If we subtract 328 from 332, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 82

Going ahead to step 6:
If we divide 45 by 82, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 7840.0
Deduct 0 from 45 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
If we divide 450 by 82, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 7840.5
Deduct 410 from 450 and we're left 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.

Step 8:
400 divided by 82 is 4 with a remainder of 72.
The next digit of our result is 4. 
Result so far: 7840.54
Subtract 328 from 400 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
720 divided by 82 is 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 7840.548
If we take 656 away from 720, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
640 divided by 82 is 7 with a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 7840.5487
Subtract 574 from 640 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 11:
660 divided by 82 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 7840.54878
Subtracting 656 from 660 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
When dividing 40 by 82, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7840.54878
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
82 goes into 400 4 times with a remainder of 72.
The next digit of our result is 4. 
Result so far: 7840.5487804
If we subtract 328 from 400, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
720 divided by 82 is 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 7840.54878048
Deduct 656 from 720 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 7840.54878048 with a balance of 6.4e-08.
