11689961 divided by 509 
Our goal is to divide 11689961 by 509.

Moving on to step 1:
509 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 509

Let's proceed to step 2:
509 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 509

Advancing to step 3:
The number 509 fits into 116 0 times, leaving a remainder of 116.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 116 after subtracting 0 from 116.
Fetch the next digit (8) from the dividend, attach it to 116 and continue: 1168 / 509

Going ahead to step 4:
The number 509 fits into 1168 2 times, leaving a remainder of 150.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1018 away from 1168, we end up with 150.
Include the next digit (9) from the dividend after 150, then repeat: 1509 / 509

Let's proceed to step 5:
When dividing 1509 by 509, we get 2 with a remainder of 491.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 1018 from 1509 to get 491.
Take the next digit (9) from the dividend and append it to 491, then repeat: 4919 / 509

On to step 6:
If we divide 4919 by 509, we get 9 and a remainder of 338.
Write down 9 as next digit of the result. 
Result so far: 229.0
If we subtract 4581 from 4919, we get 338.
Fetch the next digit (6) from the dividend, attach it to 338 and continue: 3386 / 509

Moving on to step 7:
The number 509 fits into 3386 6 times, leaving a remainder of 332.
The number 6 becomes the next digit in our result. 
Result so far: 2296.0
The remainder is 332 after subtracting 3054 from 3386.
Bring next digit (1) of the dividend behind the 332 and repeat the process: 3321 / 509

On to step 8:
509 goes into 3321 6 times with a remainder of 267.
Record the quotient 6 as the next digit in the result. 
Result so far: 22966.0
Subtracting 3054 from 3321 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 9:
When dividing 2670 by 509, we get 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 22966.5
Subtracting 2545 from 2670 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 10:
When dividing 1250 by 509, we get 2 with a remainder of 232.
Write down 2 as next digit of the result. 
Result so far: 22966.52
If we subtract 1018 from 1250, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 11:
509 can be fit into 2320 4 times, resulting in a remainder of 284.
Put 4 as the next digit of the answer. 
Result so far: 22966.524
Subtract 2036 from 2320 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 12:
When dividing 2840 by 509, we get 5 with a remainder of 295.
Record the quotient 5 as the next digit in the result. 
Result so far: 22966.5245
If we take 2545 away from 2840, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 13:
2950 divided by 509 is 5 with a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 22966.52455
If we subtract 2545 from 2950, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

The final outcome is 22966.52455, with a leftover of 0.000405.
