We divide 541838 by 21
We're looking to find how many times 21 goes into 541838.

Advancing to step 1:
5 divided by 21 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 21

On to step 2:
If we divide 54 by 21, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 42 from 54, we get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 21

On to step 3:
When dividing 121 by 21, we get 5 with a remainder of 16.
The next digit of our result is 5. 
Result so far: 25.0
If we take 105 away from 121, we end up with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 21

Let's proceed to step 4:
The number 21 fits into 168 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 258.0
Subtracting 168 from 168 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 21

On to step 5:
When dividing 3 by 21, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 2580.0
If we take 0 away from 3, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 21

Advancing to step 6:
21 can be fit into 38 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 25801.0
Subtracting 21 from 38 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.

Moving on to step 7:
When dividing 170 by 21, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 25801.8
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.

Moving on to step 8:
When dividing 20 by 21, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 25801.8
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
21 goes into 200 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 25801.809
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.

Going ahead to step 10:
When dividing 110 by 21, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 25801.8095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
The number 21 fits into 50 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 25801.80952
If we take 42 away from 50, we end up with 8.
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 12:
If we divide 80 by 21, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 25801.809523
Subtracting 63 from 80 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.

Going ahead to step 13:
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: 25801.8095238
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.

Let's proceed to step 14:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 25801.8095238
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 25801.8095238 with a remainder of 2e-08.
