We look at the division of 45904365 by 417 
The aim is to understand the frequency of 417 in 45904365.

Advancing to step 1:
4 divided by 417 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 417

Moving on to step 2:
417 goes into 45 0 times with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 417

Advancing to step 3:
459 divided by 417 is 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 417 from 459 leaves us with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 417

Advancing to step 4:
420 divided by 417 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 11.0
If we take 417 away from 420, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 417

Advancing to step 5:
417 can be fit into 34 0 times, resulting in a remainder of 34.
The next digit of our result is 0. 
Result so far: 110.0
Deduct 0 from 34 and we're left with 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 417

Step 6:
417 can be fit into 343 0 times, resulting in a remainder of 343.
Record the quotient 0 as the next digit in the result. 
Result so far: 1100.0
The remainder is 343 after subtracting 0 from 343.
Grab the next digit (6) from the dividend, add it to 343, then carry on: 3436 / 417

Going ahead to step 7:
417 can be fit into 3436 8 times, resulting in a remainder of 100.
Write down 8 as next digit of the result. 
Result so far: 11008.0
Deduct 3336 from 3436 and we're left with 100.
Bring next digit (5) of the dividend behind the 100 and repeat the process: 1005 / 417

Step 8:
If we divide 1005 by 417, we get 2 and a remainder of 171.
Put 2 as the next digit of the answer. 
Result so far: 110082.0
Subtract 834 from 1005 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 9:
If we divide 1710 by 417, we get 4 and a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 110082.4
Deduct 1668 from 1710 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
If we divide 420 by 417, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 110082.41
Deduct 417 from 420 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
The number 417 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 110082.41
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
When dividing 300 by 417, we get 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 110082.41
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 110082.41 and a remainder of 0.003.
