We look at the division of 554933 by 21 
Our goal is to divide 554933 by 21.

Going ahead to step 1:
The number 21 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 21

Advancing to step 2:
55 divided by 21 is 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 42 from 55, we get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 21

Step 3:
If we divide 134 by 21, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 126 from 134 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 21

Going ahead to step 4:
21 can be fit into 89 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 264.0
If we subtract 84 from 89, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 21

Let's proceed to step 5:
21 goes into 53 2 times with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2642.0
Deduct 42 from 53 and we're left with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 21

Advancing to step 6:
21 can be fit into 113 5 times, resulting in a remainder of 8.
The next digit of our result is 5. 
Result so far: 26425.0
Subtract 105 from 113 to get 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 7:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 26425.3
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
If we divide 170 by 21, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 26425.38
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
21 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 26425.38
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
If we divide 200 by 21, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 26425.3809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
When dividing 110 by 21, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 26425.38095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
When dividing 50 by 21, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 26425.380952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
80 divided by 21 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 26425.3809523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
The number 21 fits into 170 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 26425.38095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 26425.38095238, with a leftover of 2e-09.
