11915985 ÷ 818 
We're looking to find how many times 818 goes into 11915985.

Going ahead to step 1:
If we divide 1 by 818, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 818

On to step 2:
818 goes into 11 0 times with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 818

Let's proceed to step 3:
818 goes into 119 0 times with a remainder of 119.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 119, we end up with 119.
Include the next digit (1) from the dividend after 119, then repeat: 1191 / 818

Let's proceed to step 4:
When dividing 1191 by 818, we get 1 with a remainder of 373.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 373 after subtracting 818 from 1191.
Append the next digit (5) from the dividend to 373 and continue with: 3735 / 818

Moving on to step 5:
818 goes into 3735 4 times with a remainder of 463.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 3272 from 3735 to get 463.
Append the next digit (9) from the dividend to 463 and continue with: 4639 / 818

Moving on to step 6:
818 can be fit into 4639 5 times, resulting in a remainder of 549.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
If we subtract 4090 from 4639, we get 549.
Fetch the next digit (8) from the dividend, attach it to 549 and continue: 5498 / 818

On to step 7:
The number 818 fits into 5498 6 times, leaving a remainder of 590.
Record the quotient 6 as the next digit in the result. 
Result so far: 1456.0
If we take 4908 away from 5498, we end up with 590.
Grab the next digit (5) from the dividend, add it to 590, then carry on: 5905 / 818

Step 8:
When dividing 5905 by 818, we get 7 with a remainder of 179.
Use 7 as the next digit of our solution. 
Result so far: 14567.0
If we take 5726 away from 5905, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 9:
The number 818 fits into 1790 2 times, leaving a remainder of 154.
Put 2 as the next digit of the answer. 
Result so far: 14567.2
Deduct 1636 from 1790 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 10:
The number 818 fits into 1540 1 times, leaving a remainder of 722.
The number 1 becomes the next digit in our result. 
Result so far: 14567.21
The remainder is 722 after subtracting 818 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Moving on to step 11:
818 goes into 7220 8 times with a remainder of 676.
Put 8 as the next digit of the answer. 
Result so far: 14567.218
Deduct 6544 from 7220 and we're left with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Step 12:
818 goes into 6760 8 times with a remainder of 216.
Write down 8 as next digit of the result. 
Result so far: 14567.2188
The remainder is 216 after subtracting 6544 from 6760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The final result is 14567.2188 with a remainder of 0.00216.
