We look at the division of 51221824 by 82 
We want to figure out the number of times 51221824 can be divided by 82.

Advancing to step 1:
When dividing 5 by 82, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 82

Step 2:
When dividing 51 by 82, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 82

Advancing to step 3:
82 can be fit into 512 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 492 away from 512, we end up with 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 82

Let's proceed to step 4:
When dividing 202 by 82, we get 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 62.0
Subtract 164 from 202 to get 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 82

Let's proceed to step 5:
381 divided by 82 is 4 with a remainder of 53.
Write down 4 as next digit of the result. 
Result so far: 624.0
Subtract 328 from 381 to get 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 82

Let's proceed to step 6:
When dividing 538 by 82, we get 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 6246.0
The remainder is 46 after subtracting 492 from 538.
Append the next digit (2) from the dividend to 46 and continue with: 462 / 82

Step 7:
If we divide 462 by 82, we get 5 and a remainder of 52.
Write down 5 as next digit of the result. 
Result so far: 62465.0
Subtract 410 from 462 to get 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 82

On to step 8:
82 can be fit into 524 6 times, resulting in a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 624656.0
Subtracting 492 from 524 leaves us 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.

Going ahead to step 9:
82 goes into 320 3 times with a remainder of 74.
The next digit of our result is 3. 
Result so far: 624656.3
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.

Going ahead to step 10:
The number 82 fits into 740 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 624656.39
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.

Step 11:
20 divided by 82 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 624656.39
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
200 divided by 82 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 624656.3902
If we take 164 away from 200, we end up 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.

Advancing to step 13:
360 divided by 82 is 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 624656.39024
Subtract 328 from 360 to 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.

Step 14:
If we divide 320 by 82, we get 3 and a remainder of 74.
The number 3 becomes the next digit in our result. 
Result so far: 624656.390243
Subtracting 246 from 320 leaves us 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.

On to step 15:
740 divided by 82 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 624656.3902439
Subtract 738 from 740 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 16:
If we divide 20 by 82, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 624656.3902439
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.

After the division, we end up with 624656.3902439 and a remainder of 2e-08.
