21643 divided by 52 
We want to divide 21643 by 52.

Going ahead to step 1:
52 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 52

On to step 2:
When dividing 21 by 52, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 52

Let's proceed to step 3:
216 divided by 52 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 8 after subtracting 208 from 216.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 52

Step 4:
84 divided by 52 is 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 52 from 84 to get 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 52

On to step 5:
52 can be fit into 323 6 times, resulting in a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 416.0
If we subtract 312 from 323, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 6:
52 can be fit into 110 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 416.2
Deduct 104 from 110 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 52, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 416.21
If we take 52 away from 60, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
The number 52 fits into 80 1 times, leaving a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 416.211
If we take 52 away from 80, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 416.211 and a remainder of 0.0028.
