We divide 536650 by 21
Let's see how many times 21 fits into 536650.

Going ahead to step 1:
21 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 21

Step 2:
If we divide 53 by 21, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 42 away from 53, we end up with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 21

Moving on to step 3:
The number 21 fits into 116 5 times, leaving a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 105 from 116, we get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 21

Let's proceed to step 4:
21 can be fit into 116 5 times, resulting in a remainder of 11.
The next digit of our result is 5. 
Result so far: 255.0
If we take 105 away from 116, we end up with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 21

On to step 5:
21 goes into 115 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2555.0
Subtracting 105 from 115 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 21

On to step 6:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 25554.0
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.

Advancing to step 7:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 25554.7
If we subtract 147 from 160, we get 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.
The number 6 becomes the next digit in our result. 
Result so far: 25554.76
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.

Advancing to step 9:
21 goes into 40 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 25554.761
Deduct 21 from 40 and we're left 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.

Moving on to step 10:
When dividing 190 by 21, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 25554.7619
If we subtract 189 from 190, we get 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:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 25554.7619
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.

Advancing to step 12:
If we divide 100 by 21, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 25554.761904
Deduct 84 from 100 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.

Moving on to step 13:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 25554.7619047
Subtracting 147 from 160 leaves us 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 14:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 25554.76190476
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.

The final result is 25554.76190476 with a remainder of 4e-09.
