We look at the division of 72752725 by 417 
The aim is to understand the frequency of 417 in 72752725.

Step 1:
417 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 417

Moving on to step 2:
When dividing 72 by 417, we get 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Include the next digit (7) from the dividend after 72, then repeat: 727 / 417

On to step 3:
417 goes into 727 1 times with a remainder of 310.
The next digit of our result is 1. 
Result so far: 1.0
If we take 417 away from 727, we end up with 310.
Append the next digit (5) from the dividend to 310 and continue with: 3105 / 417

Going ahead to step 4:
417 can be fit into 3105 7 times, resulting in a remainder of 186.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 2919 from 3105, we get 186.
Include the next digit (2) from the dividend after 186, then repeat: 1862 / 417

Step 5:
417 goes into 1862 4 times with a remainder of 194.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
Subtract 1668 from 1862 to get 194.
Grab the next digit (7) from the dividend, add it to 194, then carry on: 1947 / 417

On to step 6:
1947 divided by 417 is 4 with a remainder of 279.
The next digit of our result is 4. 
Result so far: 1744.0
Subtracting 1668 from 1947 leaves us with 279.
Grab the next digit (2) from the dividend, add it to 279, then carry on: 2792 / 417

Going ahead to step 7:
If we divide 2792 by 417, we get 6 and a remainder of 290.
Write down 6 as next digit of the result. 
Result so far: 17446.0
Deduct 2502 from 2792 and we're left with 290.
Append the next digit (5) from the dividend to 290 and continue with: 2905 / 417

Advancing to step 8:
417 can be fit into 2905 6 times, resulting in a remainder of 403.
The next digit of our result is 6. 
Result so far: 174466.0
If we take 2502 away from 2905, we end up with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Let's proceed to step 9:
4030 divided by 417 is 9 with a remainder of 277.
Use 9 as the next digit of our solution. 
Result so far: 174466.9
If we subtract 3753 from 4030, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Step 10:
If we divide 2770 by 417, we get 6 and a remainder of 268.
Put 6 as the next digit of the answer. 
Result so far: 174466.96
Subtract 2502 from 2770 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 11:
If we divide 2680 by 417, we get 6 and a remainder of 178.
Write down 6 as next digit of the result. 
Result so far: 174466.966
If we subtract 2502 from 2680, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

After the division, we end up with 174466.966 and a remainder of 0.0178.
