Let's divide 544379 by 21
Let's see how many times 21 fits into 544379.

Moving on to step 1:
21 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 21

On to step 2:
The number 21 fits into 54 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 42 from 54 and we're left with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 21

Advancing to step 3:
When dividing 124 by 21, we get 5 with a remainder of 19.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 105 from 124, we get 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 21

Let's proceed to step 4:
If we divide 193 by 21, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 259.0
If we take 189 away from 193, we end up with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 21

Let's proceed to step 5:
21 can be fit into 47 2 times, resulting in a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2592.0
Deduct 42 from 47 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 21

Advancing to step 6:
The number 21 fits into 59 2 times, leaving a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 25922.0
Subtracting 42 from 59 leaves us 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.

Let's proceed to step 7:
If we divide 170 by 21, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 25922.8
Subtract 168 from 170 to 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 8:
If we divide 20 by 21, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 25922.8
If we subtract 0 from 20, we 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.

Moving on to step 9:
When dividing 200 by 21, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 25922.809
Subtracting 189 from 200 leaves us 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.

Let's proceed to step 10:
When dividing 110 by 21, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 25922.8095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
50 divided by 21 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 25922.80952
If we subtract 42 from 50, we 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.

Step 12:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 25922.809523
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.

Going ahead to step 13:
When dividing 170 by 21, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 25922.8095238
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
If we divide 20 by 21, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 25922.8095238
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.

After the division, we end up with 25922.8095238 and a remainder of 2e-08.
