We divide 73501992 by 509
We want to figure out the number of times 73501992 can be divided by 509.

Going ahead to step 1:
When dividing 7 by 509, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 509

Step 2:
The number 509 fits into 73 0 times, leaving a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Include the next digit (5) from the dividend after 73, then repeat: 735 / 509

On to step 3:
509 can be fit into 735 1 times, resulting in a remainder of 226.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 226 after subtracting 509 from 735.
Bring next digit (0) of the dividend behind the 226 and repeat the process: 2260 / 509

Step 4:
509 can be fit into 2260 4 times, resulting in a remainder of 224.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 2036 from 2260, we get 224.
Append the next digit (1) from the dividend to 224 and continue with: 2241 / 509

Moving on to step 5:
2241 divided by 509 is 4 with a remainder of 205.
Put 4 as the next digit of the answer. 
Result so far: 144.0
Subtract 2036 from 2241 to get 205.
Take the next digit (9) from the dividend and append it to 205, then repeat: 2059 / 509

Let's proceed to step 6:
509 goes into 2059 4 times with a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 1444.0
The remainder is 23 after subtracting 2036 from 2059.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 509

Moving on to step 7:
When dividing 239 by 509, we get 0 with a remainder of 239.
The number 0 becomes the next digit in our result. 
Result so far: 14440.0
Subtract 0 from 239 to get 239.
Take the next digit (2) from the dividend and append it to 239, then repeat: 2392 / 509

Advancing to step 8:
The number 509 fits into 2392 4 times, leaving a remainder of 356.
Write down 4 as next digit of the result. 
Result so far: 144404.0
If we take 2036 away from 2392, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 9:
509 can be fit into 3560 6 times, resulting in a remainder of 506.
The number 6 becomes the next digit in our result. 
Result so far: 144404.6
If we subtract 3054 from 3560, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Moving on to step 10:
If we divide 5060 by 509, we get 9 and a remainder of 479.
The next digit of our result is 9. 
Result so far: 144404.69
Subtracting 4581 from 5060 leaves us with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Going ahead to step 11:
509 can be fit into 4790 9 times, resulting in a remainder of 209.
Write down 9 as next digit of the result. 
Result so far: 144404.699
Subtracting 4581 from 4790 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

After the division, we end up with 144404.699 and a remainder of 0.0209.
