21947208 ÷ 538 
We want to divide 21947208 by 538.

Moving on to step 1:
2 divided by 538 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 538

Moving on to step 2:
If we divide 21 by 538, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 538

Let's proceed to step 3:
538 goes into 219 0 times with a remainder of 219.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 219, we get 219.
Append the next digit (4) from the dividend to 219 and continue with: 2194 / 538

Going ahead to step 4:
The number 538 fits into 2194 4 times, leaving a remainder of 42.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 2152 from 2194 leaves us with 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 538

Step 5:
538 goes into 427 0 times with a remainder of 427.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 427 to get 427.
Bring next digit (2) of the dividend behind the 427 and repeat the process: 4272 / 538

Advancing to step 6:
If we divide 4272 by 538, we get 7 and a remainder of 506.
Put 7 as the next digit of the answer. 
Result so far: 407.0
Subtract 3766 from 4272 to get 506.
Bring next digit (0) of the dividend behind the 506 and repeat the process: 5060 / 538

Moving on to step 7:
The number 538 fits into 5060 9 times, leaving a remainder of 218.
Record the quotient 9 as the next digit in the result. 
Result so far: 4079.0
Deduct 4842 from 5060 and we're left with 218.
Include the next digit (8) from the dividend after 218, then repeat: 2188 / 538

On to step 8:
2188 divided by 538 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 40794.0
If we take 2152 away from 2188, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
If we divide 360 by 538, we get 0 and a remainder of 360.
The next digit of our result is 0. 
Result so far: 40794.0
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 10:
538 goes into 3600 6 times with a remainder of 372.
The number 6 becomes the next digit in our result. 
Result so far: 40794.06
If we take 3228 away from 3600, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 11:
If we divide 3720 by 538, we get 6 and a remainder of 492.
The number 6 becomes the next digit in our result. 
Result so far: 40794.066
Deduct 3228 from 3720 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

The final result is 40794.066 with a remainder of 0.0492.
