Let's divide 582684 by 21
We want to figure out the number of times 582684 can be divided by 21.

Let's proceed to step 1:
5 divided by 21 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 21

Step 2:
If we divide 58 by 21, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 42 from 58 leaves us with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 21

Let's proceed to step 3:
162 divided by 21 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we subtract 147 from 162, we get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 21

Let's proceed to step 4:
When dividing 156 by 21, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 277.0
Deduct 147 from 156 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 21

Advancing to step 5:
21 can be fit into 98 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 2774.0
Deduct 84 from 98 and we're left with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 21

Step 6:
144 divided by 21 is 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 27746.0
Subtracting 126 from 144 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
180 divided by 21 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 27746.8
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 27746.85
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
If we divide 150 by 21, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 27746.857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 27746.8571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
If we divide 90 by 21, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 27746.85714
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 27746.857142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
When dividing 180 by 21, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 27746.8571428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
21 goes into 120 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 27746.85714285
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 27746.85714285 with a remainder of 1.5e-08.
