We're dividing 13060490 by 457 
The aim is to understand the frequency of 457 in 13060490.

Advancing to step 1:
457 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 457

Let's proceed to step 2:
13 divided by 457 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 457

Going ahead to step 3:
The number 457 fits into 130 0 times, leaving a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 130 and we're left with 130.
Bring next digit (6) of the dividend behind the 130 and repeat the process: 1306 / 457

Step 4:
457 can be fit into 1306 2 times, resulting in a remainder of 392.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 914 from 1306 to get 392.
Append the next digit (0) from the dividend to 392 and continue with: 3920 / 457

Let's proceed to step 5:
457 goes into 3920 8 times with a remainder of 264.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Deduct 3656 from 3920 and we're left with 264.
Include the next digit (4) from the dividend after 264, then repeat: 2644 / 457

Step 6:
If we divide 2644 by 457, we get 5 and a remainder of 359.
Write down 5 as next digit of the result. 
Result so far: 285.0
If we take 2285 away from 2644, we end up with 359.
Bring next digit (9) of the dividend behind the 359 and repeat the process: 3599 / 457

Going ahead to step 7:
When dividing 3599 by 457, we get 7 with a remainder of 400.
The number 7 becomes the next digit in our result. 
Result so far: 2857.0
If we subtract 3199 from 3599, we get 400.
Append the next digit (0) from the dividend to 400 and continue with: 4000 / 457

Moving on to step 8:
The number 457 fits into 4000 8 times, leaving a remainder of 344.
The next digit of our result is 8. 
Result so far: 28578.0
Subtracting 3656 from 4000 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 9:
3440 divided by 457 is 7 with a remainder of 241.
Put 7 as the next digit of the answer. 
Result so far: 28578.7
The remainder is 241 after subtracting 3199 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 10:
If we divide 2410 by 457, we get 5 and a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 28578.75
The remainder is 125 after subtracting 2285 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 11:
If we divide 1250 by 457, we get 2 and a remainder of 336.
Write down 2 as next digit of the result. 
Result so far: 28578.752
Subtract 914 from 1250 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 12:
The number 457 fits into 3360 7 times, leaving a remainder of 161.
Put 7 as the next digit of the answer. 
Result so far: 28578.7527
Subtract 3199 from 3360 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Step 13:
The number 457 fits into 1610 3 times, leaving a remainder of 239.
Record the quotient 3 as the next digit in the result. 
Result so far: 28578.75273
If we take 1371 away from 1610, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 14:
The number 457 fits into 2390 5 times, leaving a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 28578.752735
Deduct 2285 from 2390 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 15:
1050 divided by 457 is 2 with a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 28578.7527352
If we take 914 away from 1050, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 16:
457 can be fit into 1360 2 times, resulting in a remainder of 446.
The number 2 becomes the next digit in our result. 
Result so far: 28578.75273522
Deduct 914 from 1360 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

The final outcome is 28578.75273522, with a leftover of 4.46e-07.
