21303421 divided by 564 
We want to figure out the number of times 21303421 can be divided by 564.

Let's proceed to step 1:
When dividing 2 by 564, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 564

Moving on to step 2:
564 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 564

Let's proceed to step 3:
When dividing 213 by 564, we get 0 with a remainder of 213.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 213, we get 213.
Append the next digit (0) from the dividend to 213 and continue with: 2130 / 564

Let's proceed to step 4:
564 goes into 2130 3 times with a remainder of 438.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1692 away from 2130, we end up with 438.
Fetch the next digit (3) from the dividend, attach it to 438 and continue: 4383 / 564

Step 5:
When dividing 4383 by 564, we get 7 with a remainder of 435.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we subtract 3948 from 4383, we get 435.
Append the next digit (4) from the dividend to 435 and continue with: 4354 / 564

Let's proceed to step 6:
4354 divided by 564 is 7 with a remainder of 406.
Record the quotient 7 as the next digit in the result. 
Result so far: 377.0
Subtracting 3948 from 4354 leaves us with 406.
Bring next digit (2) of the dividend behind the 406 and repeat the process: 4062 / 564

Going ahead to step 7:
564 can be fit into 4062 7 times, resulting in a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 3777.0
The remainder is 114 after subtracting 3948 from 4062.
Grab the next digit (1) from the dividend, add it to 114, then carry on: 1141 / 564

Advancing to step 8:
1141 divided by 564 is 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 37772.0
Subtracting 1128 from 1141 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
564 goes into 130 0 times with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 37772.0
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
When dividing 1300 by 564, we get 2 with a remainder of 172.
Write down 2 as next digit of the result. 
Result so far: 37772.02
If we take 1128 away from 1300, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 11:
564 can be fit into 1720 3 times, resulting in a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 37772.023
If we take 1692 away from 1720, we end up 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.

Moving on to step 12:
When dividing 280 by 564, we get 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 37772.023
Deduct 0 from 280 and we're left 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 13:
The number 564 fits into 2800 4 times, leaving a remainder of 544.
Write down 4 as next digit of the result. 
Result so far: 37772.02304
If we take 2256 away from 2800, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 14:
564 goes into 5440 9 times with a remainder of 364.
The number 9 becomes the next digit in our result. 
Result so far: 37772.023049
Subtracting 5076 from 5440 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 15:
The number 564 fits into 3640 6 times, leaving a remainder of 256.
The next digit of our result is 6. 
Result so far: 37772.0230496
Subtract 3384 from 3640 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 16:
564 can be fit into 2560 4 times, resulting in a remainder of 304.
Use 4 as the next digit of our solution. 
Result so far: 37772.02304964
Subtracting 2256 from 2560 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

In conclusion, the division gives 37772.02304964 with a balance of 3.04e-07.
