We divide 582664 by 21
We want to figure out the number of times 582664 can be divided by 21.

Advancing to step 1:
When dividing 5 by 21, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 21

Let's proceed to step 2:
When dividing 58 by 21, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 42 from 58 to get 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 21

Going ahead to step 3:
If we divide 162 by 21, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 147 away from 162, we end up with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 21

Going ahead to step 4:
When dividing 156 by 21, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 277.0
Subtracting 147 from 156 leaves us with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 21

Advancing to step 5:
21 can be fit into 96 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 2774.0
If we take 84 away from 96, we end up with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 21

On to step 6:
If we divide 124 by 21, we get 5 and a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 27745.0
If we take 105 away from 124, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
21 goes into 190 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 27745.9
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 27745.9
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
If we divide 100 by 21, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 27745.904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 27745.9047
Deduct 147 from 160 and we're left 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.

Moving on to step 11:
21 goes into 130 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 27745.90476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 27745.904761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
21 goes into 190 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 27745.9047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
When dividing 10 by 21, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 27745.9047619
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 27745.9047619 with a balance of 1e-08.
