We're dividing 215066 by 51 
Our goal is to divide 215066 by 51.

Step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 51

Moving on to step 2:
If we divide 21 by 51, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 51

Going ahead to step 3:
215 divided by 51 is 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 204 from 215 and we're left with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 51

Moving on to step 4:
51 can be fit into 110 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 42.0
If we take 102 away from 110, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 51

On to step 5:
51 can be fit into 86 1 times, resulting in a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 421.0
If we subtract 51 from 86, we get 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 51

On to step 6:
51 goes into 356 6 times with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 4216.0
The remainder is 50 after subtracting 306 from 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
If we divide 500 by 51, we get 9 and a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 4216.9
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 8:
410 divided by 51 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 4216.98
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
20 divided by 51 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 4216.98
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
If we divide 200 by 51, we get 3 and a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 4216.9803
If we take 153 away from 200, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 11:
51 can be fit into 470 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 4216.98039
If we subtract 459 from 470, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
If we divide 110 by 51, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 4216.980392
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
When dividing 80 by 51, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 4216.9803921
Subtracting 51 from 80 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 14:
51 can be fit into 290 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 4216.98039215
Subtracting 255 from 290 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 4216.98039215 and a remainder of 3.5e-08.
