582710 divided by 21 
We want to divide 582710 by 21.

On to step 1:
The number 21 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
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

Step 2:
21 can be fit into 58 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 42 away from 58, we end up with 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 21

Let's proceed to step 3:
21 goes into 162 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 147 from 162 leaves us with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 21

On to step 4:
21 goes into 157 7 times with a remainder of 10.
The next digit of our result is 7. 
Result so far: 277.0
Subtracting 147 from 157 leaves us with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 21

Going ahead to step 5:
21 goes into 101 4 times with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 2774.0
Subtract 84 from 101 to get 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 21

On to step 6:
When dividing 170 by 21, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 27748.0
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
If we divide 20 by 21, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 27748.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 21 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 27748.09
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
110 divided by 21 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 27748.095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
50 divided by 21 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 27748.0952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
80 divided by 21 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 27748.09523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
When dividing 170 by 21, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 27748.095238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
The number 21 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 27748.095238
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 27748.09523809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 27748.09523809 with a balance of 1.1e-08.
