Let's divide 67548549 by 449
The aim is to understand the frequency of 449 in 67548549.

Moving on to step 1:
When dividing 6 by 449, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 449

Step 2:
When dividing 67 by 449, we get 0 with a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 449

Advancing to step 3:
The number 449 fits into 675 1 times, leaving a remainder of 226.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 449 from 675 to get 226.
Take the next digit (4) from the dividend and append it to 226, then repeat: 2264 / 449

Step 4:
2264 divided by 449 is 5 with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 19 after subtracting 2245 from 2264.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 449

Advancing to step 5:
When dividing 198 by 449, we get 0 with a remainder of 198.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
The remainder is 198 after subtracting 0 from 198.
Fetch the next digit (5) from the dividend, attach it to 198 and continue: 1985 / 449

Step 6:
449 can be fit into 1985 4 times, resulting in a remainder of 189.
Write down 4 as next digit of the result. 
Result so far: 1504.0
Deduct 1796 from 1985 and we're left with 189.
Include the next digit (4) from the dividend after 189, then repeat: 1894 / 449

Let's proceed to step 7:
1894 divided by 449 is 4 with a remainder of 98.
The next digit of our result is 4. 
Result so far: 15044.0
Deduct 1796 from 1894 and we're left with 98.
Take the next digit (9) from the dividend and append it to 98, then repeat: 989 / 449

Moving on to step 8:
The number 449 fits into 989 2 times, leaving a remainder of 91.
Record the quotient 2 as the next digit in the result. 
Result so far: 150442.0
If we take 898 away from 989, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 9:
910 divided by 449 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 150442.2
Subtracting 898 from 910 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
The number 449 fits into 120 0 times, leaving a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 150442.2
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
449 can be fit into 1200 2 times, resulting in a remainder of 302.
The next digit of our result is 2. 
Result so far: 150442.202
Subtract 898 from 1200 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 12:
449 goes into 3020 6 times with a remainder of 326.
Put 6 as the next digit of the answer. 
Result so far: 150442.2026
If we subtract 2694 from 3020, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 13:
449 goes into 3260 7 times with a remainder of 117.
Record the quotient 7 as the next digit in the result. 
Result so far: 150442.20267
Deduct 3143 from 3260 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 14:
449 can be fit into 1170 2 times, resulting in a remainder of 272.
The next digit of our result is 2. 
Result so far: 150442.202672
Subtract 898 from 1170 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 15:
If we divide 2720 by 449, we get 6 and a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 150442.2026726
Subtracting 2694 from 2720 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 16:
The number 449 fits into 260 0 times, leaving a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 150442.2026726
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.

The final outcome is 150442.2026726, with a leftover of 2.6e-07.
