We divide 536193 by 21
We want to divide 536193 by 21.

Advancing to step 1:
21 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 21

Moving on to step 2:
If we divide 53 by 21, we get 2 and a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 42 from 53 to get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 21

Let's proceed to step 3:
116 divided by 21 is 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 105 from 116 and we're left with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 21

Advancing to step 4:
If we divide 111 by 21, we get 5 and a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 255.0
If we subtract 105 from 111, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 21

Let's proceed to step 5:
21 can be fit into 69 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 2553.0
Deduct 63 from 69 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 21

Going ahead to step 6:
The number 21 fits into 63 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 25533.0
If we subtract 63 from 63, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
21 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25533.0
If we subtract 0 from 0, we get 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:
0 divided by 21 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 25533.0
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 final result is 25533.0 with a remainder of 0.0.
