We divide 97156412 by 449
The aim is to understand the frequency of 449 in 97156412.

Moving on to step 1:
When dividing 9 by 449, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 449

Moving on to step 2:
When dividing 97 by 449, we get 0 with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Append the next digit (1) from the dividend to 97 and continue with: 971 / 449

On to step 3:
449 can be fit into 971 2 times, resulting in a remainder of 73.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 898 from 971, we get 73.
Grab the next digit (5) from the dividend, add it to 73, then carry on: 735 / 449

On to step 4:
735 divided by 449 is 1 with a remainder of 286.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 449 from 735, we get 286.
Grab the next digit (6) from the dividend, add it to 286, then carry on: 2866 / 449

On to step 5:
The number 449 fits into 2866 6 times, leaving a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 216.0
If we subtract 2694 from 2866, we get 172.
Grab the next digit (4) from the dividend, add it to 172, then carry on: 1724 / 449

Moving on to step 6:
If we divide 1724 by 449, we get 3 and a remainder of 377.
The next digit of our result is 3. 
Result so far: 2163.0
Subtract 1347 from 1724 to get 377.
Fetch the next digit (1) from the dividend, attach it to 377 and continue: 3771 / 449

On to step 7:
If we divide 3771 by 449, we get 8 and a remainder of 179.
Record the quotient 8 as the next digit in the result. 
Result so far: 21638.0
If we take 3592 away from 3771, we end up with 179.
Fetch the next digit (2) from the dividend, attach it to 179 and continue: 1792 / 449

Let's proceed to step 8:
449 can be fit into 1792 3 times, resulting in a remainder of 445.
The number 3 becomes the next digit in our result. 
Result so far: 216383.0
If we take 1347 away from 1792, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 9:
The number 449 fits into 4450 9 times, leaving a remainder of 409.
The number 9 becomes the next digit in our result. 
Result so far: 216383.9
If we take 4041 away from 4450, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 10:
449 can be fit into 4090 9 times, resulting in a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 216383.99
Subtract 4041 from 4090 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 216383.99 and a remainder of 0.049.
