We divide 91752846 by 449
The aim is to understand the frequency of 449 in 91752846.

Advancing to step 1:
When dividing 9 by 449, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 449

On to step 2:
When dividing 91 by 449, we get 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Grab the next digit (7) from the dividend, add it to 91, then carry on: 917 / 449

Going ahead to step 3:
449 goes into 917 2 times with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 898 away from 917, we end up with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 449

Moving on to step 4:
449 can be fit into 195 0 times, resulting in a remainder of 195.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 195, we end up with 195.
Append the next digit (2) from the dividend to 195 and continue with: 1952 / 449

Moving on to step 5:
449 can be fit into 1952 4 times, resulting in a remainder of 156.
Put 4 as the next digit of the answer. 
Result so far: 204.0
The remainder is 156 after subtracting 1796 from 1952.
Bring next digit (8) of the dividend behind the 156 and repeat the process: 1568 / 449

Let's proceed to step 6:
449 goes into 1568 3 times with a remainder of 221.
Put 3 as the next digit of the answer. 
Result so far: 2043.0
Subtracting 1347 from 1568 leaves us with 221.
Grab the next digit (4) from the dividend, add it to 221, then carry on: 2214 / 449

Going ahead to step 7:
449 goes into 2214 4 times with a remainder of 418.
The number 4 becomes the next digit in our result. 
Result so far: 20434.0
The remainder is 418 after subtracting 1796 from 2214.
Take the next digit (6) from the dividend and append it to 418, then repeat: 4186 / 449

Let's proceed to step 8:
449 goes into 4186 9 times with a remainder of 145.
The number 9 becomes the next digit in our result. 
Result so far: 204349.0
The remainder is 145 after subtracting 4041 from 4186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 9:
The number 449 fits into 1450 3 times, leaving a remainder of 103.
The next digit of our result is 3. 
Result so far: 204349.3
Subtract 1347 from 1450 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 10:
449 can be fit into 1030 2 times, resulting in a remainder of 132.
Use 2 as the next digit of our solution. 
Result so far: 204349.32
Deduct 898 from 1030 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 11:
449 goes into 1320 2 times with a remainder of 422.
The number 2 becomes the next digit in our result. 
Result so far: 204349.322
If we subtract 898 from 1320, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

After the division, we end up with 204349.322 and a remainder of 0.0422.
