We divide 50009590 by 725
The aim is to understand the frequency of 725 in 50009590.

On to step 1:
If we divide 5 by 725, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 725

Going ahead to step 2:
725 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 725

On to step 3:
725 can be fit into 500 0 times, resulting in a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 500, we get 500.
Include the next digit (0) from the dividend after 500, then repeat: 5000 / 725

Going ahead to step 4:
When dividing 5000 by 725, we get 6 with a remainder of 650.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 4350 from 5000 and we're left with 650.
Bring next digit (9) of the dividend behind the 650 and repeat the process: 6509 / 725

Going ahead to step 5:
725 goes into 6509 8 times with a remainder of 709.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
If we subtract 5800 from 6509, we get 709.
Include the next digit (5) from the dividend after 709, then repeat: 7095 / 725

Going ahead to step 6:
When dividing 7095 by 725, we get 9 with a remainder of 570.
Use 9 as the next digit of our solution. 
Result so far: 689.0
Subtracting 6525 from 7095 leaves us with 570.
Append the next digit (9) from the dividend to 570 and continue with: 5709 / 725

Moving on to step 7:
5709 divided by 725 is 7 with a remainder of 634.
Record the quotient 7 as the next digit in the result. 
Result so far: 6897.0
If we take 5075 away from 5709, we end up with 634.
Grab the next digit (0) from the dividend, add it to 634, then carry on: 6340 / 725

Moving on to step 8:
6340 divided by 725 is 8 with a remainder of 540.
Record the quotient 8 as the next digit in the result. 
Result so far: 68978.0
Subtracting 5800 from 6340 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 9:
725 can be fit into 5400 7 times, resulting in a remainder of 325.
The number 7 becomes the next digit in our result. 
Result so far: 68978.7
If we take 5075 away from 5400, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 10:
725 goes into 3250 4 times with a remainder of 350.
Write down 4 as next digit of the result. 
Result so far: 68978.74
If we subtract 2900 from 3250, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 11:
3500 divided by 725 is 4 with a remainder of 600.
The number 4 becomes the next digit in our result. 
Result so far: 68978.744
Subtracting 2900 from 3500 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

After the division, we end up with 68978.744 and a remainder of 0.06.
