Let's divide 11960991 by 509
We want to figure out the number of times 11960991 can be divided by 509.

Let's proceed to step 1:
509 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 509

Going ahead to step 2:
When dividing 11 by 509, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 509

On to step 3:
The number 509 fits into 119 0 times, leaving a remainder of 119.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 119, we get 119.
Fetch the next digit (6) from the dividend, attach it to 119 and continue: 1196 / 509

Step 4:
When dividing 1196 by 509, we get 2 with a remainder of 178.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 178 after subtracting 1018 from 1196.
Fetch the next digit (0) from the dividend, attach it to 178 and continue: 1780 / 509

Advancing to step 5:
509 can be fit into 1780 3 times, resulting in a remainder of 253.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 253 after subtracting 1527 from 1780.
Take the next digit (9) from the dividend and append it to 253, then repeat: 2539 / 509

On to step 6:
If we divide 2539 by 509, we get 4 and a remainder of 503.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
The remainder is 503 after subtracting 2036 from 2539.
Grab the next digit (9) from the dividend, add it to 503, then carry on: 5039 / 509

Moving on to step 7:
509 can be fit into 5039 9 times, resulting in a remainder of 458.
The next digit of our result is 9. 
Result so far: 2349.0
Subtracting 4581 from 5039 leaves us with 458.
Grab the next digit (1) from the dividend, add it to 458, then carry on: 4581 / 509

Step 8:
509 can be fit into 4581 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 23499.0
If we take 4581 away from 4581, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
509 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23499.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
509 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 23499.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 23499.0, and the remainder is 0.0.
