216 can be fit into 45 0 times, resulting in a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 216

Moving on to step 3:
216 goes into 450 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 432 from 450, we get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 216

Step 4:
187 divided by 216 is 0 with a remainder of 187.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 187 leaves us with 187.
Bring next digit (3) of the dividend behind the 187 and repeat the process: 1873 / 216

Let's proceed to step 5:
216 can be fit into 1873 8 times, resulting in a remainder of 145.
Use 8 as the next digit of our solution. 
Result so far: 208.0
Deduct 1728 from 1873 and we're left with 145.
Bring next digit (5) of the dividend behind the 145 and repeat the process: 1455 / 216

Advancing to step 6:
1455 divided by 216 is 6 with a remainder of 159.
Record the quotient 6 as the next digit in the result. 
Result so far: 2086.0
If we subtract 1296 from 1455, we get 159.
Include the next digit (7) from the dividend after 159, then repeat: 1597 / 216

Step 7:
The number 216 fits into 1597 7 times, leaving a remainder of 85.
The number 7 becomes the next digit in our result. 
Result so far: 20867.0
Deduct 1512 from 1597 and we're left with 85.
Include the next digit (6) from the dividend after 85, then repeat: 856 / 216

On to step 8:
216 goes into 856 3 times with a remainder of 208.
The number 3 becomes the next digit in our result. 
Result so far: 208673.0
If we take 648 away from 856, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 9:
216 goes into 2080 9 times with a remainder of 136.
Write down 9 as next digit of the result. 
Result so far: 208673.9
The remainder is 136 after subtracting 1944 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 10:
216 goes into 1360 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 208673.96
Subtracting 1296 from 1360 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
The number 216 fits into 640 2 times, leaving a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 208673.962
Subtract 432 from 640 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 12:
When dividing 2080 by 216, we get 9 with a remainder of 136.
Record the quotient 9 as the next digit in the result. 
Result so far: 208673.9629
If we subtract 1944 from 2080, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 13:
216 can be fit into 1360 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 208673.96296
Subtracting 1296 from 1360 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
The number 216 fits into 640 2 times, leaving a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 208673.962962
Deduct 432 from 640 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 15:
216 goes into 2080 9 times with a remainder of 136.
The number 9 becomes the next digit in our result. 
Result so far: 208673.9629629
Deduct 1944 from 2080 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 16:
216 goes into 1360 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 208673.96296296
Subtracting 1296 from 1360 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 208673.96296296 and a remainder of 6.4e-08.
