78797724 divided by 449 
The aim is to understand the frequency of 449 in 78797724.

Step 1:
449 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 449

Going ahead to step 2:
If we divide 78 by 449, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 449

Going ahead to step 3:
787 divided by 449 is 1 with a remainder of 338.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 338 after subtracting 449 from 787.
Take the next digit (9) from the dividend and append it to 338, then repeat: 3389 / 449

Going ahead to step 4:
3389 divided by 449 is 7 with a remainder of 246.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 3143 from 3389, we get 246.
Append the next digit (7) from the dividend to 246 and continue with: 2467 / 449

Step 5:
When dividing 2467 by 449, we get 5 with a remainder of 222.
Put 5 as the next digit of the answer. 
Result so far: 175.0
Deduct 2245 from 2467 and we're left with 222.
Bring next digit (7) of the dividend behind the 222 and repeat the process: 2227 / 449

Step 6:
2227 divided by 449 is 4 with a remainder of 431.
The number 4 becomes the next digit in our result. 
Result so far: 1754.0
Subtracting 1796 from 2227 leaves us with 431.
Include the next digit (2) from the dividend after 431, then repeat: 4312 / 449

On to step 7:
If we divide 4312 by 449, we get 9 and a remainder of 271.
Use 9 as the next digit of our solution. 
Result so far: 17549.0
If we subtract 4041 from 4312, we get 271.
Take the next digit (4) from the dividend and append it to 271, then repeat: 2714 / 449

Moving on to step 8:
2714 divided by 449 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 175496.0
Deduct 2694 from 2714 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 449, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 175496.0
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
449 goes into 2000 4 times with a remainder of 204.
The next digit of our result is 4. 
Result so far: 175496.04
The remainder is 204 after subtracting 1796 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 11:
449 can be fit into 2040 4 times, resulting in a remainder of 244.
Record the quotient 4 as the next digit in the result. 
Result so far: 175496.044
If we take 1796 away from 2040, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Our division results in 175496.044 with a remaining 0.0244.
