We divide 75917233 by 509
The aim is to understand the frequency of 509 in 75917233.

Step 1:
The number 509 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 509

Advancing to step 2:
The number 509 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Append the next digit (9) from the dividend to 75 and continue with: 759 / 509

Going ahead to step 3:
If we divide 759 by 509, we get 1 and a remainder of 250.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 509 away from 759, we end up with 250.
Fetch the next digit (1) from the dividend, attach it to 250 and continue: 2501 / 509

Step 4:
509 goes into 2501 4 times with a remainder of 465.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 2036 from 2501, we get 465.
Append the next digit (7) from the dividend to 465 and continue with: 4657 / 509

Advancing to step 5:
509 goes into 4657 9 times with a remainder of 76.
The next digit of our result is 9. 
Result so far: 149.0
Subtract 4581 from 4657 to get 76.
Append the next digit (2) from the dividend to 76 and continue with: 762 / 509

Advancing to step 6:
When dividing 762 by 509, we get 1 with a remainder of 253.
The number 1 becomes the next digit in our result. 
Result so far: 1491.0
Deduct 509 from 762 and we're left with 253.
Take the next digit (3) from the dividend and append it to 253, then repeat: 2533 / 509

Advancing to step 7:
509 goes into 2533 4 times with a remainder of 497.
Put 4 as the next digit of the answer. 
Result so far: 14914.0
The remainder is 497 after subtracting 2036 from 2533.
Take the next digit (3) from the dividend and append it to 497, then repeat: 4973 / 509

Advancing to step 8:
4973 divided by 509 is 9 with a remainder of 392.
Write down 9 as next digit of the result. 
Result so far: 149149.0
The remainder is 392 after subtracting 4581 from 4973.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 9:
When dividing 3920 by 509, we get 7 with a remainder of 357.
Write down 7 as next digit of the result. 
Result so far: 149149.7
If we take 3563 away from 3920, we end up with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Step 10:
509 can be fit into 3570 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 149149.77
If we take 3563 away from 3570, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 149149.77 with a remaining 0.007.
