533311 ÷ 21 
We want to divide 533311 by 21.

Advancing to step 1:
21 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 21

Going ahead to step 2:
21 goes into 53 2 times with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 42 from 53 leaves us with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 21

Advancing to step 3:
21 goes into 113 5 times with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 105 from 113 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 21

Moving on to step 4:
When dividing 83 by 21, we get 3 with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 253.0
Subtract 63 from 83 to get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 21

Step 5:
When dividing 201 by 21, we get 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 2539.0
The remainder is 12 after subtracting 189 from 201.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 21

Step 6:
21 can be fit into 121 5 times, resulting in a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 25395.0
Deduct 105 from 121 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 25395.7
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 25395.76
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 25395.761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
If we divide 190 by 21, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 25395.7619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
10 divided by 21 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 25395.7619
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
100 divided by 21 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 25395.761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 25395.7619047
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 14:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 25395.76190476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 25395.76190476 with a remainder of 4e-09.
