We're dividing 73270761 by 449 
The aim is to understand the frequency of 449 in 73270761.

Going ahead to step 1:
449 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 449

On to step 2:
449 goes into 73 0 times with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Include the next digit (2) from the dividend after 73, then repeat: 732 / 449

Going ahead to step 3:
If we divide 732 by 449, we get 1 and a remainder of 283.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 283 after subtracting 449 from 732.
Include the next digit (7) from the dividend after 283, then repeat: 2837 / 449

On to step 4:
If we divide 2837 by 449, we get 6 and a remainder of 143.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 2694 from 2837 leaves us with 143.
Take the next digit (0) from the dividend and append it to 143, then repeat: 1430 / 449

Going ahead to step 5:
The number 449 fits into 1430 3 times, leaving a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
Deduct 1347 from 1430 and we're left with 83.
Fetch the next digit (7) from the dividend, attach it to 83 and continue: 837 / 449

Advancing to step 6:
If we divide 837 by 449, we get 1 and a remainder of 388.
Record the quotient 1 as the next digit in the result. 
Result so far: 1631.0
Deduct 449 from 837 and we're left with 388.
Fetch the next digit (6) from the dividend, attach it to 388 and continue: 3886 / 449

Going ahead to step 7:
If we divide 3886 by 449, we get 8 and a remainder of 294.
Write down 8 as next digit of the result. 
Result so far: 16318.0
Subtract 3592 from 3886 to get 294.
Take the next digit (1) from the dividend and append it to 294, then repeat: 2941 / 449

Step 8:
When dividing 2941 by 449, we get 6 with a remainder of 247.
The next digit of our result is 6. 
Result so far: 163186.0
Subtract 2694 from 2941 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 9:
449 can be fit into 2470 5 times, resulting in a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 163186.5
If we take 2245 away from 2470, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 10:
449 can be fit into 2250 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 163186.55
The remainder is 5 after subtracting 2245 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 163186.55 with a remaining 0.005.
