We look at the division of 18901510 by 216 
We want to figure out the number of times 18901510 can be divided by 216.

Moving on to step 1:
1 divided by 216 is 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.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 216

Step 2:
When dividing 18 by 216, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 216

On to step 3:
The number 216 fits into 189 0 times, leaving a remainder of 189.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 189 leaves us with 189.
Fetch the next digit (0) from the dividend, attach it to 189 and continue: 1890 / 216

Moving on to step 4:
When dividing 1890 by 216, we get 8 with a remainder of 162.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 162 after subtracting 1728 from 1890.
Append the next digit (1) from the dividend to 162 and continue with: 1621 / 216

Step 5:
When dividing 1621 by 216, we get 7 with a remainder of 109.
The next digit of our result is 7. 
Result so far: 87.0
Subtract 1512 from 1621 to get 109.
Take the next digit (5) from the dividend and append it to 109, then repeat: 1095 / 216

On to step 6:
When dividing 1095 by 216, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 875.0
The remainder is 15 after subtracting 1080 from 1095.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 216

Advancing to step 7:
When dividing 151 by 216, we get 0 with a remainder of 151.
The next digit of our result is 0. 
Result so far: 8750.0
Subtract 0 from 151 to get 151.
Take the next digit (0) from the dividend and append it to 151, then repeat: 1510 / 216

Step 8:
216 can be fit into 1510 6 times, resulting in a remainder of 214.
The next digit of our result is 6. 
Result so far: 87506.0
Subtracting 1296 from 1510 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 9:
2140 divided by 216 is 9 with a remainder of 196.
The next digit of our result is 9. 
Result so far: 87506.9
Subtract 1944 from 2140 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 10:
When dividing 1960 by 216, we get 9 with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 87506.99
Subtract 1944 from 1960 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 87506.99, with a leftover of 0.016.
