We're dividing 566097 by 21 
Our goal is to divide 566097 by 21.

On 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.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 21

Let's proceed to step 2:
21 goes into 56 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 42 from 56, we get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 21

Advancing to step 3:
When dividing 146 by 21, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 26.0
If we take 126 away from 146, we end up with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 21

Going ahead to step 4:
The number 21 fits into 200 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 269.0
Deduct 189 from 200 and we're left with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 21

On to step 5:
21 goes into 119 5 times with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 2695.0
If we subtract 105 from 119, we get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 21

Let's proceed to step 6:
If we divide 147 by 21, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 26957.0
Subtracting 147 from 147 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 21 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 26957.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 21, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26957.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 26957.0, and the remainder is 0.0.
