We look at the division of 43554503 by 457 
The aim is to understand the frequency of 457 in 43554503.

Moving on to step 1:
4 divided by 457 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 457

Step 2:
457 can be fit into 43 0 times, resulting in a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 457

Step 3:
The number 457 fits into 435 0 times, leaving a remainder of 435.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 435, we end up with 435.
Append the next digit (5) from the dividend to 435 and continue with: 4355 / 457

Advancing to step 4:
4355 divided by 457 is 9 with a remainder of 242.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 4113 from 4355 and we're left with 242.
Fetch the next digit (4) from the dividend, attach it to 242 and continue: 2424 / 457

Advancing to step 5:
2424 divided by 457 is 5 with a remainder of 139.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
The remainder is 139 after subtracting 2285 from 2424.
Bring next digit (5) of the dividend behind the 139 and repeat the process: 1395 / 457

Going ahead to step 6:
The number 457 fits into 1395 3 times, leaving a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 953.0
If we subtract 1371 from 1395, we get 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 457

Let's proceed to step 7:
457 goes into 240 0 times with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 9530.0
Subtract 0 from 240 to get 240.
Fetch the next digit (3) from the dividend, attach it to 240 and continue: 2403 / 457

On to step 8:
When dividing 2403 by 457, we get 5 with a remainder of 118.
Record the quotient 5 as the next digit in the result. 
Result so far: 95305.0
Subtract 2285 from 2403 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 9:
1180 divided by 457 is 2 with a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 95305.2
Deduct 914 from 1180 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 10:
When dividing 2660 by 457, we get 5 with a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 95305.25
Subtracting 2285 from 2660 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 11:
457 goes into 3750 8 times with a remainder of 94.
Record the quotient 8 as the next digit in the result. 
Result so far: 95305.258
Subtract 3656 from 3750 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 12:
457 can be fit into 940 2 times, resulting in a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 95305.2582
Subtract 914 from 940 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
When dividing 260 by 457, we get 0 with a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 95305.2582
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 14:
457 goes into 2600 5 times with a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 95305.258205
If we take 2285 away from 2600, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 15:
457 can be fit into 3150 6 times, resulting in a remainder of 408.
The number 6 becomes the next digit in our result. 
Result so far: 95305.2582056
Subtracting 2742 from 3150 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 16:
4080 divided by 457 is 8 with a remainder of 424.
Put 8 as the next digit of the answer. 
Result so far: 95305.25820568
If we take 3656 away from 4080, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

The final result is 95305.25820568 with a remainder of 4.24e-07.
