We're dividing 69171618 by 509 
Let's see how many times 509 fits into 69171618.

Let's proceed to step 1:
If we divide 6 by 509, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 509

On to step 2:
The number 509 fits into 69 0 times, leaving a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Append the next digit (1) from the dividend to 69 and continue with: 691 / 509

Moving on to step 3:
691 divided by 509 is 1 with a remainder of 182.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 509 from 691 to get 182.
Include the next digit (7) from the dividend after 182, then repeat: 1827 / 509

Step 4:
If we divide 1827 by 509, we get 3 and a remainder of 300.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1527 away from 1827, we end up with 300.
Grab the next digit (1) from the dividend, add it to 300, then carry on: 3001 / 509

On to step 5:
When dividing 3001 by 509, we get 5 with a remainder of 456.
The next digit of our result is 5. 
Result so far: 135.0
Subtract 2545 from 3001 to get 456.
Take the next digit (6) from the dividend and append it to 456, then repeat: 4566 / 509

Advancing to step 6:
509 goes into 4566 8 times with a remainder of 494.
Write down 8 as next digit of the result. 
Result so far: 1358.0
Subtract 4072 from 4566 to get 494.
Take the next digit (1) from the dividend and append it to 494, then repeat: 4941 / 509

On to step 7:
The number 509 fits into 4941 9 times, leaving a remainder of 360.
The next digit of our result is 9. 
Result so far: 13589.0
If we subtract 4581 from 4941, we get 360.
Take the next digit (8) from the dividend and append it to 360, then repeat: 3608 / 509

Going ahead to step 8:
509 goes into 3608 7 times with a remainder of 45.
The next digit of our result is 7. 
Result so far: 135897.0
If we subtract 3563 from 3608, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
450 divided by 509 is 0 with a remainder of 450.
The number 0 becomes the next digit in our result. 
Result so far: 135897.0
Deduct 0 from 450 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 10:
When dividing 4500 by 509, we get 8 with a remainder of 428.
Write down 8 as next digit of the result. 
Result so far: 135897.08
If we take 4072 away from 4500, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 11:
When dividing 4280 by 509, we get 8 with a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 135897.088
If we subtract 4072 from 4280, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Our division results in 135897.088 with a remaining 0.0208.
