21546 divided by 63 
We're looking to find how many times 63 goes into 21546.

On to step 1:
2 divided by 63 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 63

Let's proceed to step 2:
63 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 63

Going ahead to step 3:
63 goes into 215 3 times with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 189 from 215 leaves us with 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 63

Advancing to step 4:
264 divided by 63 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 252 from 264 leaves us with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 63

Moving on to step 5:
63 can be fit into 126 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 342.0
The remainder is 0 after subtracting 126 from 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 6:
63 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 342.0
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.

Moving on to step 7:
When dividing 0 by 63, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 342.0
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.

The quotient of the division is 342.0, and the remainder is 0.0.
