We look at the division of 21320342 by 783 
We want to figure out the number of times 21320342 can be divided by 783.

Step 1:
783 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 783

Advancing to step 2:
783 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 783

Let's proceed to step 3:
213 divided by 783 is 0 with a remainder of 213.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 213, we end up with 213.
Take the next digit (2) from the dividend and append it to 213, then repeat: 2132 / 783

Step 4:
783 goes into 2132 2 times with a remainder of 566.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1566 from 2132, we get 566.
Bring next digit (0) of the dividend behind the 566 and repeat the process: 5660 / 783

Moving on to step 5:
If we divide 5660 by 783, we get 7 and a remainder of 179.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 5481 from 5660, we get 179.
Grab the next digit (3) from the dividend, add it to 179, then carry on: 1793 / 783

Advancing to step 6:
783 goes into 1793 2 times with a remainder of 227.
The number 2 becomes the next digit in our result. 
Result so far: 272.0
Subtract 1566 from 1793 to get 227.
Take the next digit (4) from the dividend and append it to 227, then repeat: 2274 / 783

Step 7:
2274 divided by 783 is 2 with a remainder of 708.
The number 2 becomes the next digit in our result. 
Result so far: 2722.0
The remainder is 708 after subtracting 1566 from 2274.
Append the next digit (2) from the dividend to 708 and continue with: 7082 / 783

Moving on to step 8:
The number 783 fits into 7082 9 times, leaving a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 27229.0
If we take 7047 away from 7082, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
783 can be fit into 350 0 times, resulting in a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 27229.0
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 10:
If we divide 3500 by 783, we get 4 and a remainder of 368.
Record the quotient 4 as the next digit in the result. 
Result so far: 27229.04
If we subtract 3132 from 3500, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 11:
783 can be fit into 3680 4 times, resulting in a remainder of 548.
The next digit of our result is 4. 
Result so far: 27229.044
Subtracting 3132 from 3680 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

The final result is 27229.044 with a remainder of 0.0548.
