We're dividing 638144 by 82 
We want to figure out the number of times 638144 can be divided by 82.

Going ahead to step 1:
82 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 82

Moving on to step 2:
If we divide 63 by 82, we get 0 and a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 82

Let's proceed to step 3:
The number 82 fits into 638 7 times, leaving a remainder of 64.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 64 after subtracting 574 from 638.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 82

Step 4:
The number 82 fits into 641 7 times, leaving a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we take 574 away from 641, we end up with 67.
Bring next digit (4) of the dividend behind the 67 and repeat the process: 674 / 82

Advancing to step 5:
The number 82 fits into 674 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 778.0
Deduct 656 from 674 and we're left with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 82

On to step 6:
When dividing 184 by 82, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 7782.0
Deduct 164 from 184 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
82 goes into 200 2 times with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 7782.2
Deduct 164 from 200 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
82 goes into 360 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7782.24
If we subtract 328 from 360, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
320 divided by 82 is 3 with a remainder of 74.
Write down 3 as next digit of the result. 
Result so far: 7782.243
Subtract 246 from 320 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.

Step 10:
If we divide 740 by 82, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 7782.2439
The remainder is 2 after subtracting 738 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
82 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7782.2439
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
The number 82 fits into 200 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 7782.243902
Subtract 164 from 200 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
360 divided by 82 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 7782.2439024
The remainder is 32 after subtracting 328 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
If we divide 320 by 82, we get 3 and a remainder of 74.
The next digit of our result is 3. 
Result so far: 7782.24390243
If we take 246 away from 320, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final outcome is 7782.24390243, with a leftover of 7.4e-08.
