We look at the division of 15817644 by 216 
Our goal is to divide 15817644 by 216.

Going ahead to step 1:
When dividing 1 by 216, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 216

Advancing to step 2:
216 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 216

Moving on to step 3:
216 goes into 158 0 times with a remainder of 158.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 158 after subtracting 0 from 158.
Fetch the next digit (1) from the dividend, attach it to 158 and continue: 1581 / 216

Let's proceed to step 4:
If we divide 1581 by 216, we get 7 and a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 69 after subtracting 1512 from 1581.
Fetch the next digit (7) from the dividend, attach it to 69 and continue: 697 / 216

Going ahead to step 5:
The number 216 fits into 697 3 times, leaving a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtracting 648 from 697 leaves us with 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 216

Going ahead to step 6:
496 divided by 216 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 732.0
If we take 432 away from 496, we end up with 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 216

Step 7:
216 can be fit into 644 2 times, resulting in a remainder of 212.
Put 2 as the next digit of the answer. 
Result so far: 7322.0
The remainder is 212 after subtracting 432 from 644.
Include the next digit (4) from the dividend after 212, then repeat: 2124 / 216

On to step 8:
The number 216 fits into 2124 9 times, leaving a remainder of 180.
Put 9 as the next digit of the answer. 
Result so far: 73229.0
Subtracting 1944 from 2124 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 9:
The number 216 fits into 1800 8 times, leaving a remainder of 72.
The next digit of our result is 8. 
Result so far: 73229.8
Subtract 1728 from 1800 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 10:
216 can be fit into 720 3 times, resulting in a remainder of 72.
The next digit of our result is 3. 
Result so far: 73229.83
If we take 648 away from 720, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 11:
If we divide 720 by 216, we get 3 and a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 73229.833
Subtract 648 from 720 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 73229.833 with a remaining 0.0072.
