216279 ÷ 57 
Our goal is to divide 216279 by 57.

Step 1:
2 divided by 57 is 0 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.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 57

Moving on to step 2:
21 divided by 57 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 57

Let's proceed to step 3:
The number 57 fits into 216 3 times, leaving a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 171 from 216, we get 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 57

Let's proceed to step 4:
When dividing 452 by 57, we get 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtracting 399 from 452 leaves us with 53.
Bring next digit (7) of the dividend behind the 53 and repeat the process: 537 / 57

Going ahead to step 5:
537 divided by 57 is 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 379.0
Deduct 513 from 537 and we're left with 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 57

Let's proceed to step 6:
249 divided by 57 is 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 3794.0
Subtract 228 from 249 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
If we divide 210 by 57, we get 3 and a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 3794.3
Deduct 171 from 210 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 8:
390 divided by 57 is 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 3794.36
Deduct 342 from 390 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
The number 57 fits into 480 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 3794.368
The remainder is 24 after subtracting 456 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
57 goes into 240 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 3794.3684
Subtracting 228 from 240 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
When dividing 120 by 57, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 3794.36842
Subtract 114 from 120 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
The number 57 fits into 60 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 3794.368421
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
When dividing 30 by 57, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 3794.368421
If we subtract 0 from 30, we get 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 14:
If we divide 300 by 57, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3794.36842105
Deduct 285 from 300 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.

The final outcome is 3794.36842105, with a leftover of 1.5e-08.
