We look at the division of 21359926 by 756 
We're looking to find how many times 756 goes into 21359926.

Going ahead to step 1:
If we divide 2 by 756, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 756

Let's proceed to step 2:
When dividing 21 by 756, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 756

Step 3:
756 goes into 213 0 times with a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Bring next digit (5) of the dividend behind the 213 and repeat the process: 2135 / 756

Advancing to step 4:
If we divide 2135 by 756, we get 2 and a remainder of 623.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1512 away from 2135, we end up with 623.
Take the next digit (9) from the dividend and append it to 623, then repeat: 6239 / 756

Going ahead to step 5:
The number 756 fits into 6239 8 times, leaving a remainder of 191.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 6048 away from 6239, we end up with 191.
Take the next digit (9) from the dividend and append it to 191, then repeat: 1919 / 756

Advancing to step 6:
If we divide 1919 by 756, we get 2 and a remainder of 407.
The next digit of our result is 2. 
Result so far: 282.0
Subtracting 1512 from 1919 leaves us with 407.
Fetch the next digit (2) from the dividend, attach it to 407 and continue: 4072 / 756

Step 7:
756 goes into 4072 5 times with a remainder of 292.
Write down 5 as next digit of the result. 
Result so far: 2825.0
Subtract 3780 from 4072 to get 292.
Include the next digit (6) from the dividend after 292, then repeat: 2926 / 756

Step 8:
If we divide 2926 by 756, we get 3 and a remainder of 658.
The number 3 becomes the next digit in our result. 
Result so far: 28253.0
If we subtract 2268 from 2926, we get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Let's proceed to step 9:
6580 divided by 756 is 8 with a remainder of 532.
The number 8 becomes the next digit in our result. 
Result so far: 28253.8
If we take 6048 away from 6580, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Let's proceed to step 10:
When dividing 5320 by 756, we get 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 28253.87
The remainder is 28 after subtracting 5292 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
The number 756 fits into 280 0 times, leaving a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 28253.87
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
When dividing 2800 by 756, we get 3 with a remainder of 532.
The next digit of our result is 3. 
Result so far: 28253.8703
The remainder is 532 after subtracting 2268 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 13:
756 can be fit into 5320 7 times, resulting in a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 28253.87037
Subtract 5292 from 5320 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
The number 756 fits into 280 0 times, leaving a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 28253.87037
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 15:
756 can be fit into 2800 3 times, resulting in a remainder of 532.
Put 3 as the next digit of the answer. 
Result so far: 28253.8703703
If we take 2268 away from 2800, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 16:
5320 divided by 756 is 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 28253.87037037
Deduct 5292 from 5320 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 28253.87037037, with a leftover of 2.8e-08.
