Let's divide 21437686 by 82
We're looking to find how many times 82 goes into 21437686.

Going ahead to step 1:
When dividing 2 by 82, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 82

On to step 2:
21 divided by 82 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 82

Going ahead to step 3:
When dividing 214 by 82, we get 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 164 from 214 to get 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 82

On to step 4:
If we divide 503 by 82, we get 6 and a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we take 492 away from 503, we end up with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 82

Step 5:
If we divide 117 by 82, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 261.0
If we subtract 82 from 117, we get 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 82

Moving on to step 6:
The number 82 fits into 356 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 2614.0
If we take 328 away from 356, we end up with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 82

Going ahead to step 7:
The number 82 fits into 288 3 times, leaving a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 26143.0
Subtracting 246 from 288 leaves us with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 82

Step 8:
If we divide 426 by 82, we get 5 and a remainder of 16.
The next digit of our result is 5. 
Result so far: 261435.0
Deduct 410 from 426 and we're left with 16.
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 9:
82 can be fit into 160 1 times, resulting in a remainder of 78.
Put 1 as the next digit of the answer. 
Result so far: 261435.1
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.

Advancing to step 10:
If we divide 780 by 82, we get 9 and a remainder of 42.
The next digit of our result is 9. 
Result so far: 261435.19
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.

On to step 11:
420 divided by 82 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 261435.195
If we subtract 410 from 420, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 82, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 261435.1951
Subtracting 82 from 100 leaves us 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.

On to step 13:
When dividing 180 by 82, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 261435.19512
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.

Let's proceed to step 14:
When dividing 160 by 82, we get 1 with a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 261435.195121
If we subtract 82 from 160, we 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.

Step 15:
The number 82 fits into 780 9 times, leaving a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 261435.1951219
Subtract 738 from 780 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 16:
420 divided by 82 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 261435.19512195
The remainder is 10 after subtracting 410 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 261435.19512195, and the remainder is 1e-08.
