21153884 ÷ 541 
We want to divide 21153884 by 541.

Advancing to step 1:
2 divided by 541 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 541

Let's proceed to step 2:
If we divide 21 by 541, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 541

Moving on to step 3:
If we divide 211 by 541, we get 0 and a remainder of 211.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 211 after subtracting 0 from 211.
Grab the next digit (5) from the dividend, add it to 211, then carry on: 2115 / 541

Let's proceed to step 4:
541 goes into 2115 3 times with a remainder of 492.
The next digit of our result is 3. 
Result so far: 3.0
If we take 1623 away from 2115, we end up with 492.
Take the next digit (3) from the dividend and append it to 492, then repeat: 4923 / 541

Moving on to step 5:
4923 divided by 541 is 9 with a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 4869 from 4923 to get 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 541

Let's proceed to step 6:
When dividing 548 by 541, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 391.0
If we subtract 541 from 548, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 541

Let's proceed to step 7:
78 divided by 541 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 3910.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 541

Step 8:
541 can be fit into 784 1 times, resulting in a remainder of 243.
Put 1 as the next digit of the answer. 
Result so far: 39101.0
Subtract 541 from 784 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 9:
The number 541 fits into 2430 4 times, leaving a remainder of 266.
The next digit of our result is 4. 
Result so far: 39101.4
Deduct 2164 from 2430 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 10:
If we divide 2660 by 541, we get 4 and a remainder of 496.
The number 4 becomes the next digit in our result. 
Result so far: 39101.44
Subtract 2164 from 2660 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

The final outcome is 39101.44, with a leftover of 0.496.
