We divide 554323 by 21
Let's see how many times 21 fits into 554323.

Let's proceed to step 1:
5 divided by 21 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 21

Moving on to step 2:
If we divide 55 by 21, we get 2 and a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 42 away from 55, we end up with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 21

Advancing to step 3:
21 goes into 134 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 8 after subtracting 126 from 134.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 21

Step 4:
21 goes into 83 3 times with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 263.0
Subtract 63 from 83 to get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 21

Let's proceed to step 5:
If we divide 202 by 21, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 2639.0
If we subtract 189 from 202, we get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 21

Moving on to step 6:
21 goes into 133 6 times with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 26396.0
If we subtract 126 from 133, 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.

On to step 7:
21 can be fit into 70 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 26396.3
Deduct 63 from 70 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.

Let's proceed to step 8:
When dividing 70 by 21, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 26396.33
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.

Our division results in 26396.33 with a remaining 0.007.
