Let's divide 73180609 by 519
The aim is to understand the frequency of 519 in 73180609.

On to step 1:
7 divided by 519 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 519

Going ahead to step 2:
73 divided by 519 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 519

Step 3:
731 divided by 519 is 1 with a remainder of 212.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 519 from 731 leaves us with 212.
Take the next digit (8) from the dividend and append it to 212, then repeat: 2128 / 519

Let's proceed to step 4:
The number 519 fits into 2128 4 times, leaving a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 52 after subtracting 2076 from 2128.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 519

Advancing to step 5:
520 divided by 519 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 141.0
If we take 519 away from 520, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 519

Moving on to step 6:
16 divided by 519 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 1410.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 519

Let's proceed to step 7:
519 goes into 160 0 times with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 14100.0
If we take 0 away from 160, we end up with 160.
Grab the next digit (9) from the dividend, add it to 160, then carry on: 1609 / 519

Moving on to step 8:
If we divide 1609 by 519, we get 3 and a remainder of 52.
The next digit of our result is 3. 
Result so far: 141003.0
The remainder is 52 after subtracting 1557 from 1609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
519 goes into 520 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 141003.1
Subtract 519 from 520 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
519 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 141003.1
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
When dividing 100 by 519, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 141003.1
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 141003.1 with a balance of 0.01.
