We look at the division of 4349474 by 457 
The aim is to understand the frequency of 457 in 4349474.

Going ahead to step 1:
457 can be fit into 4 0 times, resulting in 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.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 457

Step 2:
When dividing 43 by 457, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 457

Step 3:
The number 457 fits into 434 0 times, leaving a remainder of 434.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 434, we end up with 434.
Take the next digit (9) from the dividend and append it to 434, then repeat: 4349 / 457

Advancing to step 4:
When dividing 4349 by 457, we get 9 with a remainder of 236.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 4113 from 4349 and we're left with 236.
Fetch the next digit (4) from the dividend, attach it to 236 and continue: 2364 / 457

On to step 5:
457 goes into 2364 5 times with a remainder of 79.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we subtract 2285 from 2364, we get 79.
Include the next digit (7) from the dividend after 79, then repeat: 797 / 457

Going ahead to step 6:
If we divide 797 by 457, we get 1 and a remainder of 340.
The number 1 becomes the next digit in our result. 
Result so far: 951.0
Subtracting 457 from 797 leaves us with 340.
Bring next digit (4) of the dividend behind the 340 and repeat the process: 3404 / 457

Advancing to step 7:
3404 divided by 457 is 7 with a remainder of 205.
The number 7 becomes the next digit in our result. 
Result so far: 9517.0
Subtract 3199 from 3404 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 8:
The number 457 fits into 2050 4 times, leaving a remainder of 222.
The next digit of our result is 4. 
Result so far: 9517.4
If we subtract 1828 from 2050, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 9:
The number 457 fits into 2220 4 times, leaving a remainder of 392.
The next digit of our result is 4. 
Result so far: 9517.44
Deduct 1828 from 2220 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final outcome is 9517.44, with a leftover of 0.392.
