583130 ÷ 21 
Our goal is to divide 583130 by 21.

Going ahead to step 1:
5 divided by 21 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 21

Moving on to step 2:
21 goes into 58 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 42 from 58 to get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 21

Moving on to step 3:
21 can be fit into 163 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 27.0
The remainder is 16 after subtracting 147 from 163.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 21

Advancing to step 4:
21 goes into 161 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 277.0
Subtracting 147 from 161 leaves us with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 21

Advancing to step 5:
21 goes into 143 6 times with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 2776.0
Subtracting 126 from 143 leaves us with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 21

Advancing to step 6:
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: 27768.0
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 21, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 27768.0
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.

Moving on to step 8:
21 goes into 200 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 27768.09
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.

Advancing to step 9:
When dividing 110 by 21, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 27768.095
The remainder is 5 after subtracting 105 from 110.
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:
When dividing 50 by 21, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 27768.0952
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
If we divide 80 by 21, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 27768.09523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
170 divided by 21 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 27768.095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
21 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 27768.095238
Deduct 0 from 20 and we're left 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:
When dividing 200 by 21, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 27768.09523809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 27768.09523809 with a remaining 1.1e-08.
