We divide 554526 by 21
Let's see how many times 21 fits into 554526.

Let's proceed to step 1:
When dividing 5 by 21, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 21

On to step 2:
When dividing 55 by 21, we get 2 with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 42 from 55 to get 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 21

Going ahead to step 3:
21 goes into 134 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we take 126 away from 134, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 21

Moving on to step 4:
21 goes into 85 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 264.0
Subtract 84 from 85 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 21

Moving on to step 5:
21 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 2640.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 21

Advancing to step 6:
If we divide 126 by 21, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 26406.0
Deduct 126 from 126 and we're left 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.

Advancing to step 7:
If we divide 0 by 21, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 26406.0
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:
When dividing 0 by 21, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26406.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 26406.0 with a remaining 0.0.
