We look at the division of 18453045 by 216 
Let's see how many times 216 fits into 18453045.

Advancing to step 1:
216 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 216

Let's proceed to step 2:
The number 216 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 216

Moving on to step 3:
216 can be fit into 184 0 times, resulting in a remainder of 184.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 184, we get 184.
Append the next digit (5) from the dividend to 184 and continue with: 1845 / 216

On to step 4:
216 goes into 1845 8 times with a remainder of 117.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 117 after subtracting 1728 from 1845.
Fetch the next digit (3) from the dividend, attach it to 117 and continue: 1173 / 216

Step 5:
The number 216 fits into 1173 5 times, leaving a remainder of 93.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtracting 1080 from 1173 leaves us with 93.
Include the next digit (0) from the dividend after 93, then repeat: 930 / 216

Advancing to step 6:
The number 216 fits into 930 4 times, leaving a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 854.0
Deduct 864 from 930 and we're left with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 216

Moving on to step 7:
216 goes into 664 3 times with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 8543.0
If we subtract 648 from 664, we get 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 216

Let's proceed to step 8:
When dividing 165 by 216, we get 0 with a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 85430.0
The remainder is 165 after subtracting 0 from 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 9:
The number 216 fits into 1650 7 times, leaving a remainder of 138.
The number 7 becomes the next digit in our result. 
Result so far: 85430.7
Subtract 1512 from 1650 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 10:
1380 divided by 216 is 6 with a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 85430.76
Subtracting 1296 from 1380 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
The number 216 fits into 840 3 times, leaving a remainder of 192.
Record the quotient 3 as the next digit in the result. 
Result so far: 85430.763
Deduct 648 from 840 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 12:
216 can be fit into 1920 8 times, resulting in a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 85430.7638
Deduct 1728 from 1920 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 13:
216 goes into 1920 8 times with a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 85430.76388
If we subtract 1728 from 1920, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Our division results in 85430.76388 with a remaining 0.000192.
