215384 ÷ 55 
We want to figure out the number of times 215384 can be divided by 55.

Let's proceed to step 1:
55 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 55

Moving on to step 2:
55 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 55

Going ahead to step 3:
55 goes into 215 3 times with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 165 away from 215, we end up with 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 55

Advancing to step 4:
503 divided by 55 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 495 from 503 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 55

Let's proceed to step 5:
55 goes into 88 1 times with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 391.0
Subtracting 55 from 88 leaves us with 33.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 55

On to step 6:
334 divided by 55 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3916.0
Subtract 330 from 334 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
55 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3916.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
If we divide 400 by 55, we get 7 and a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 3916.07
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
55 goes into 150 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 3916.072
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
400 divided by 55 is 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 3916.0727
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
If we divide 150 by 55, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 3916.07272
If we take 110 away from 150, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
The number 55 fits into 400 7 times, leaving a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 3916.072727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
The number 55 fits into 150 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 3916.0727272
Deduct 110 from 150 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 3916.07272727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 3916.07272727 with a remaining 1.5e-08.
