215214 ÷ 54 
Let's see how many times 54 fits into 215214.

On to step 1:
54 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
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 / 54

Going ahead to step 2:
If we divide 21 by 54, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 54

Step 3:
The number 54 fits into 215 3 times, leaving a remainder of 53.
The next digit of our result is 3. 
Result so far: 3.0
If we take 162 away from 215, we end up with 53.
Grab the next digit (2) from the dividend, add it to 53, then carry on: 532 / 54

Let's proceed to step 4:
54 goes into 532 9 times with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 486 away from 532, we end up with 46.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 54

Let's proceed to step 5:
If we divide 461 by 54, we get 8 and a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 398.0
Deduct 432 from 461 and we're left with 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 54

Moving on to step 6:
54 can be fit into 294 5 times, resulting in a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 3985.0
Subtracting 270 from 294 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
54 can be fit into 240 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 3985.4
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
When dividing 240 by 54, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 3985.44
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 3985.44, with a leftover of 0.024.
