21559744 ÷ 393 
We want to divide 21559744 by 393.

Going ahead to step 1:
If we divide 2 by 393, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 393

Advancing to step 2:
When dividing 21 by 393, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 393

Moving on to step 3:
The number 393 fits into 215 0 times, leaving a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 215, we end up with 215.
Grab the next digit (5) from the dividend, add it to 215, then carry on: 2155 / 393

Step 4:
If we divide 2155 by 393, we get 5 and a remainder of 190.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 1965 from 2155 leaves us with 190.
Take the next digit (9) from the dividend and append it to 190, then repeat: 1909 / 393

Step 5:
If we divide 1909 by 393, we get 4 and a remainder of 337.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we take 1572 away from 1909, we end up with 337.
Append the next digit (7) from the dividend to 337 and continue with: 3377 / 393

Let's proceed to step 6:
The number 393 fits into 3377 8 times, leaving a remainder of 233.
Record the quotient 8 as the next digit in the result. 
Result so far: 548.0
The remainder is 233 after subtracting 3144 from 3377.
Fetch the next digit (4) from the dividend, attach it to 233 and continue: 2334 / 393

Going ahead to step 7:
The number 393 fits into 2334 5 times, leaving a remainder of 369.
Write down 5 as next digit of the result. 
Result so far: 5485.0
Subtracting 1965 from 2334 leaves us with 369.
Bring next digit (4) of the dividend behind the 369 and repeat the process: 3694 / 393

Moving on to step 8:
393 goes into 3694 9 times with a remainder of 157.
The next digit of our result is 9. 
Result so far: 54859.0
Subtracting 3537 from 3694 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 9:
393 goes into 1570 3 times with a remainder of 391.
Record the quotient 3 as the next digit in the result. 
Result so far: 54859.3
If we take 1179 away from 1570, we end up with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Going ahead to step 10:
When dividing 3910 by 393, we get 9 with a remainder of 373.
Write down 9 as next digit of the result. 
Result so far: 54859.39
If we subtract 3537 from 3910, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 11:
3730 divided by 393 is 9 with a remainder of 193.
Put 9 as the next digit of the answer. 
Result so far: 54859.399
Subtract 3537 from 3730 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

In conclusion, the division gives 54859.399 with a balance of 0.0193.
