583467 ÷ 21 
We're looking to find how many times 21 goes into 583467.

Going ahead 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
Deduct 0 from 5 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 21

Going ahead to step 2:
The number 21 fits into 58 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 16 after subtracting 42 from 58.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 21

Going ahead to step 3:
When dividing 163 by 21, we get 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtract 147 from 163 to get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 21

Step 4:
21 can be fit into 164 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 277.0
If we take 147 away from 164, we end up with 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 21

Step 5:
176 divided by 21 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 2778.0
If we subtract 168 from 176, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 21

On to step 6:
If we divide 87 by 21, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 27784.0
Deduct 84 from 87 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
21 goes into 30 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 27784.1
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
When dividing 90 by 21, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 27784.14
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
60 divided by 21 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 27784.142
Subtract 42 from 60 to 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.

On to step 10:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 27784.1428
Deduct 168 from 180 and we're left 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.

Let's proceed to step 11:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 27784.14285
Deduct 105 from 120 and we're left 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.

On to step 12:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 27784.142857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
When dividing 30 by 21, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 27784.1428571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 27784.14285714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 27784.14285714, and the remainder is 6e-09.
