Let's divide 20936968 by 817
We want to figure out the number of times 20936968 can be divided by 817.

Going ahead to step 1:
817 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 817

On to step 2:
817 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 817

On to step 3:
When dividing 209 by 817, we get 0 with a remainder of 209.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 209 after subtracting 0 from 209.
Fetch the next digit (3) from the dividend, attach it to 209 and continue: 2093 / 817

Let's proceed to step 4:
If we divide 2093 by 817, we get 2 and a remainder of 459.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 459 after subtracting 1634 from 2093.
Grab the next digit (6) from the dividend, add it to 459, then carry on: 4596 / 817

Going ahead to step 5:
When dividing 4596 by 817, we get 5 with a remainder of 511.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 4085 from 4596, we get 511.
Grab the next digit (9) from the dividend, add it to 511, then carry on: 5119 / 817

Step 6:
When dividing 5119 by 817, we get 6 with a remainder of 217.
Use 6 as the next digit of our solution. 
Result so far: 256.0
The remainder is 217 after subtracting 4902 from 5119.
Append the next digit (6) from the dividend to 217 and continue with: 2176 / 817

Step 7:
When dividing 2176 by 817, we get 2 with a remainder of 542.
Use 2 as the next digit of our solution. 
Result so far: 2562.0
Subtract 1634 from 2176 to get 542.
Append the next digit (8) from the dividend to 542 and continue with: 5428 / 817

Let's proceed to step 8:
If we divide 5428 by 817, we get 6 and a remainder of 526.
Put 6 as the next digit of the answer. 
Result so far: 25626.0
Subtracting 4902 from 5428 leaves us with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

On to step 9:
The number 817 fits into 5260 6 times, leaving a remainder of 358.
Record the quotient 6 as the next digit in the result. 
Result so far: 25626.6
Subtracting 4902 from 5260 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 10:
If we divide 3580 by 817, we get 4 and a remainder of 312.
Use 4 as the next digit of our solution. 
Result so far: 25626.64
Subtract 3268 from 3580 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 11:
3120 divided by 817 is 3 with a remainder of 669.
Write down 3 as next digit of the result. 
Result so far: 25626.643
Subtract 2451 from 3120 to get 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

On to step 12:
If we divide 6690 by 817, we get 8 and a remainder of 154.
The number 8 becomes the next digit in our result. 
Result so far: 25626.6438
If we take 6536 away from 6690, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 13:
The number 817 fits into 1540 1 times, leaving a remainder of 723.
Put 1 as the next digit of the answer. 
Result so far: 25626.64381
If we subtract 817 from 1540, we get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Let's proceed to step 14:
817 goes into 7230 8 times with a remainder of 694.
The number 8 becomes the next digit in our result. 
Result so far: 25626.643818
Subtract 6536 from 7230 to get 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Advancing to step 15:
6940 divided by 817 is 8 with a remainder of 404.
The number 8 becomes the next digit in our result. 
Result so far: 25626.6438188
The remainder is 404 after subtracting 6536 from 6940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Our division results in 25626.6438188 with a remaining 4.04e-06.
