We're dividing 21798323 by 905 
Let's see how many times 905 fits into 21798323.

Moving on to step 1:
If we divide 2 by 905, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 905

Moving on to step 2:
The number 905 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 905

Moving on to step 3:
When dividing 217 by 905, we get 0 with a remainder of 217.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Bring next digit (9) of the dividend behind the 217 and repeat the process: 2179 / 905

Moving on to step 4:
When dividing 2179 by 905, we get 2 with a remainder of 369.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 369 after subtracting 1810 from 2179.
Include the next digit (8) from the dividend after 369, then repeat: 3698 / 905

Let's proceed to step 5:
If we divide 3698 by 905, we get 4 and a remainder of 78.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 78 after subtracting 3620 from 3698.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 905

Let's proceed to step 6:
905 can be fit into 783 0 times, resulting in a remainder of 783.
The next digit of our result is 0. 
Result so far: 240.0
If we take 0 away from 783, we end up with 783.
Include the next digit (2) from the dividend after 783, then repeat: 7832 / 905

Moving on to step 7:
If we divide 7832 by 905, we get 8 and a remainder of 592.
Record the quotient 8 as the next digit in the result. 
Result so far: 2408.0
Subtract 7240 from 7832 to get 592.
Bring next digit (3) of the dividend behind the 592 and repeat the process: 5923 / 905

On to step 8:
905 goes into 5923 6 times with a remainder of 493.
The number 6 becomes the next digit in our result. 
Result so far: 24086.0
Deduct 5430 from 5923 and we're left with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

On to step 9:
If we divide 4930 by 905, we get 5 and a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 24086.5
If we subtract 4525 from 4930, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 10:
If we divide 4050 by 905, we get 4 and a remainder of 430.
Use 4 as the next digit of our solution. 
Result so far: 24086.54
Subtracting 3620 from 4050 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 11:
4300 divided by 905 is 4 with a remainder of 680.
Put 4 as the next digit of the answer. 
Result so far: 24086.544
Subtract 3620 from 4300 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Our division results in 24086.544 with a remaining 0.068.
