16615109 ÷ 108 
We're looking to find how many times 108 goes into 16615109.

Let's proceed to step 1:
108 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 108

Step 2:
108 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 108

On to step 3:
108 can be fit into 166 1 times, resulting in a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 108 from 166 to get 58.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 108

Advancing to step 4:
The number 108 fits into 581 5 times, leaving a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 41 after subtracting 540 from 581.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 108

Going ahead to step 5:
The number 108 fits into 415 3 times, leaving a remainder of 91.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Deduct 324 from 415 and we're left with 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 108

Moving on to step 6:
If we divide 911 by 108, we get 8 and a remainder of 47.
Write down 8 as next digit of the result. 
Result so far: 1538.0
The remainder is 47 after subtracting 864 from 911.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 108

Moving on to step 7:
The number 108 fits into 470 4 times, leaving a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 15384.0
Subtract 432 from 470 to get 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 108

Step 8:
108 goes into 389 3 times with a remainder of 65.
Put 3 as the next digit of the answer. 
Result so far: 153843.0
Deduct 324 from 389 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
When dividing 650 by 108, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 153843.6
The remainder is 2 after subtracting 648 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
The number 108 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 153843.6
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.

Step 11:
The number 108 fits into 200 1 times, leaving a remainder of 92.
Put 1 as the next digit of the answer. 
Result so far: 153843.601
Deduct 108 from 200 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 12:
108 can be fit into 920 8 times, resulting in a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 153843.6018
Deduct 864 from 920 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
The number 108 fits into 560 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 153843.60185
Subtracting 540 from 560 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
108 can be fit into 200 1 times, resulting in a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 153843.601851
Deduct 108 from 200 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 15:
920 divided by 108 is 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 153843.6018518
Subtract 864 from 920 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 16:
108 can be fit into 560 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 153843.60185185
Subtracting 540 from 560 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 153843.60185185, with a leftover of 2e-08.
