We're dividing 18717812 by 515 
We want to figure out the number of times 18717812 can be divided by 515.

On to step 1:
1 divided by 515 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 515

Advancing to step 2:
When dividing 18 by 515, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 515

Let's proceed to step 3:
515 goes into 187 0 times with a remainder of 187.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 187 after subtracting 0 from 187.
Take the next digit (1) from the dividend and append it to 187, then repeat: 1871 / 515

Going ahead to step 4:
When dividing 1871 by 515, we get 3 with a remainder of 326.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 326 after subtracting 1545 from 1871.
Bring next digit (7) of the dividend behind the 326 and repeat the process: 3267 / 515

Going ahead to step 5:
515 goes into 3267 6 times with a remainder of 177.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 3090 away from 3267, we end up with 177.
Bring next digit (8) of the dividend behind the 177 and repeat the process: 1778 / 515

Moving on to step 6:
515 goes into 1778 3 times with a remainder of 233.
Put 3 as the next digit of the answer. 
Result so far: 363.0
Deduct 1545 from 1778 and we're left with 233.
Fetch the next digit (1) from the dividend, attach it to 233 and continue: 2331 / 515

On to step 7:
The number 515 fits into 2331 4 times, leaving a remainder of 271.
Write down 4 as next digit of the result. 
Result so far: 3634.0
Subtract 2060 from 2331 to get 271.
Take the next digit (2) from the dividend and append it to 271, then repeat: 2712 / 515

Moving on to step 8:
If we divide 2712 by 515, we get 5 and a remainder of 137.
Use 5 as the next digit of our solution. 
Result so far: 36345.0
If we subtract 2575 from 2712, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 9:
The number 515 fits into 1370 2 times, leaving a remainder of 340.
Record the quotient 2 as the next digit in the result. 
Result so far: 36345.2
Subtracting 1030 from 1370 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 10:
If we divide 3400 by 515, we get 6 and a remainder of 310.
Write down 6 as next digit of the result. 
Result so far: 36345.26
If we take 3090 away from 3400, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 11:
3100 divided by 515 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 36345.266
If we subtract 3090 from 3100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 36345.266 with a remainder of 0.001.
