Let's divide 552832 by 21
Let's see how many times 21 fits into 552832.

Moving on to step 1:
The number 21 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 21

Step 2:
The number 21 fits into 55 2 times, leaving a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 42 from 55, we get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 21

Step 3:
The number 21 fits into 132 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 26.0
Deduct 126 from 132 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 21

Let's proceed to step 4:
21 can be fit into 68 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 263.0
Deduct 63 from 68 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 21

Advancing to step 5:
21 can be fit into 53 2 times, resulting in a remainder of 11.
The next digit of our result is 2. 
Result so far: 2632.0
If we subtract 42 from 53, we get 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 21

Advancing to step 6:
21 can be fit into 112 5 times, resulting in a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 26325.0
Deduct 105 from 112 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
21 goes into 70 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 26325.3
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
If we divide 70 by 21, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 26325.33
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 26325.33 with a remainder of 0.007.
