568716 ÷ 21 
We're looking to find how many times 21 goes into 568716.

On to step 1:
21 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 21

On to step 2:
If we divide 56 by 21, we get 2 and a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 42 from 56 leaves us with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 21

Moving on to step 3:
21 goes into 148 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we subtract 147 from 148, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 21

Advancing to step 4:
When dividing 17 by 21, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 270.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 21

Advancing to step 5:
When dividing 171 by 21, we get 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 2708.0
If we take 168 away from 171, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 21

Moving on to step 6:
When dividing 36 by 21, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 27081.0
The remainder is 15 after subtracting 21 from 36.
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 7:
If we divide 150 by 21, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 27081.7
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
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: 27081.71
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.

On to step 9:
90 divided by 21 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 27081.714
Subtracting 84 from 90 leaves us 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.

On to step 10:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 27081.7142
Deduct 42 from 60 and we're left 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.

Advancing to step 11:
21 goes into 180 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 27081.71428
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.

Let's proceed to step 12:
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: 27081.714285
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 13:
When dividing 150 by 21, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 27081.7142857
The remainder is 3 after subtracting 147 from 150.
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 14:
When dividing 30 by 21, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 27081.71428571
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.

The final outcome is 27081.71428571, with a leftover of 9e-09.
