12186415 ÷ 272 
We want to figure out the number of times 12186415 can be divided by 272.

Step 1:
When dividing 1 by 272, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 272

Let's proceed to step 2:
272 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 272

On to step 3:
The number 272 fits into 121 0 times, leaving a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 121 after subtracting 0 from 121.
Bring next digit (8) of the dividend behind the 121 and repeat the process: 1218 / 272

Step 4:
272 can be fit into 1218 4 times, resulting in a remainder of 130.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 1088 from 1218, we get 130.
Append the next digit (6) from the dividend to 130 and continue with: 1306 / 272

Step 5:
When dividing 1306 by 272, we get 4 with a remainder of 218.
The next digit of our result is 4. 
Result so far: 44.0
Deduct 1088 from 1306 and we're left with 218.
Take the next digit (4) from the dividend and append it to 218, then repeat: 2184 / 272

Step 6:
2184 divided by 272 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 448.0
If we take 2176 away from 2184, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 272

Step 7:
272 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 4480.0
Subtract 0 from 81 to get 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 272

Let's proceed to step 8:
The number 272 fits into 815 2 times, leaving a remainder of 271.
Write down 2 as next digit of the result. 
Result so far: 44802.0
If we take 544 away from 815, we end up with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 9:
272 can be fit into 2710 9 times, resulting in a remainder of 262.
The number 9 becomes the next digit in our result. 
Result so far: 44802.9
The remainder is 262 after subtracting 2448 from 2710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 10:
When dividing 2620 by 272, we get 9 with a remainder of 172.
The next digit of our result is 9. 
Result so far: 44802.99
Subtract 2448 from 2620 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Our division results in 44802.99 with a remaining 0.172.
