We divide 21871 by 55
We're looking to find how many times 55 goes into 21871.

Let's proceed to step 1:
55 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 55

Advancing to step 2:
When dividing 21 by 55, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 55

Going ahead to step 3:
When dividing 218 by 55, we get 3 with a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 165 from 218 leaves us with 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 55

Moving on to step 4:
55 goes into 537 9 times with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 495 from 537 to get 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 55

Step 5:
55 can be fit into 421 7 times, resulting in a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 397.0
Subtract 385 from 421 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 6:
55 can be fit into 360 6 times, resulting in a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 397.6
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
55 can be fit into 300 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 397.65
If we take 275 away from 300, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
If we divide 250 by 55, we get 4 and a remainder of 30.
The next digit of our result is 4. 
Result so far: 397.654
The remainder is 30 after subtracting 220 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
The number 55 fits into 300 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 397.6545
Deduct 275 from 300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
The number 55 fits into 250 4 times, leaving a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 397.65454
The remainder is 30 after subtracting 220 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
55 can be fit into 300 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 397.654545
Subtract 275 from 300 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
55 goes into 250 4 times with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 397.6545454
Deduct 220 from 250 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
55 goes into 300 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 397.65454545
Deduct 275 from 300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 397.65454545 and a remainder of 2.5e-08.
