Let's divide 57830020 by 449
The aim is to understand the frequency of 449 in 57830020.

Moving on to step 1:
When dividing 5 by 449, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 449

Moving on to step 2:
The number 449 fits into 57 0 times, leaving a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 449

Step 3:
578 divided by 449 is 1 with a remainder of 129.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 449 away from 578, we end up with 129.
Take the next digit (3) from the dividend and append it to 129, then repeat: 1293 / 449

Step 4:
When dividing 1293 by 449, we get 2 with a remainder of 395.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 898 away from 1293, we end up with 395.
Append the next digit (0) from the dividend to 395 and continue with: 3950 / 449

Step 5:
When dividing 3950 by 449, we get 8 with a remainder of 358.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtracting 3592 from 3950 leaves us with 358.
Fetch the next digit (0) from the dividend, attach it to 358 and continue: 3580 / 449

Going ahead to step 6:
3580 divided by 449 is 7 with a remainder of 437.
Record the quotient 7 as the next digit in the result. 
Result so far: 1287.0
If we take 3143 away from 3580, we end up with 437.
Fetch the next digit (2) from the dividend, attach it to 437 and continue: 4372 / 449

Step 7:
If we divide 4372 by 449, we get 9 and a remainder of 331.
The number 9 becomes the next digit in our result. 
Result so far: 12879.0
If we subtract 4041 from 4372, we get 331.
Include the next digit (0) from the dividend after 331, then repeat: 3310 / 449

Advancing to step 8:
449 goes into 3310 7 times with a remainder of 167.
The next digit of our result is 7. 
Result so far: 128797.0
Deduct 3143 from 3310 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 9:
When dividing 1670 by 449, we get 3 with a remainder of 323.
Record the quotient 3 as the next digit in the result. 
Result so far: 128797.3
Subtracting 1347 from 1670 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Step 10:
If we divide 3230 by 449, we get 7 and a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 128797.37
Subtract 3143 from 3230 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 11:
449 can be fit into 870 1 times, resulting in a remainder of 421.
Put 1 as the next digit of the answer. 
Result so far: 128797.371
If we take 449 away from 870, we end up with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Let's proceed to step 12:
If we divide 4210 by 449, we get 9 and a remainder of 169.
Write down 9 as next digit of the result. 
Result so far: 128797.3719
Subtracting 4041 from 4210 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 13:
If we divide 1690 by 449, we get 3 and a remainder of 343.
Put 3 as the next digit of the answer. 
Result so far: 128797.37193
Subtract 1347 from 1690 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 14:
The number 449 fits into 3430 7 times, leaving a remainder of 287.
Write down 7 as next digit of the result. 
Result so far: 128797.371937
If we subtract 3143 from 3430, we get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Moving on to step 15:
The number 449 fits into 2870 6 times, leaving a remainder of 176.
The next digit of our result is 6. 
Result so far: 128797.3719376
Deduct 2694 from 2870 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 16:
449 can be fit into 1760 3 times, resulting in a remainder of 413.
Record the quotient 3 as the next digit in the result. 
Result so far: 128797.37193763
The remainder is 413 after subtracting 1347 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

After the division, we end up with 128797.37193763 and a remainder of 4.13e-07.
