We look at the division of 33310375 by 449 
The aim is to understand the frequency of 449 in 33310375.

On to step 1:
If we divide 3 by 449, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 449

On to step 2:
When dividing 33 by 449, we get 0 with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 449

Advancing to step 3:
449 goes into 333 0 times with a remainder of 333.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 333 leaves us with 333.
Append the next digit (1) from the dividend to 333 and continue with: 3331 / 449

Going ahead to step 4:
When dividing 3331 by 449, we get 7 with a remainder of 188.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 3143 from 3331, we get 188.
Append the next digit (0) from the dividend to 188 and continue with: 1880 / 449

On to step 5:
1880 divided by 449 is 4 with a remainder of 84.
The next digit of our result is 4. 
Result so far: 74.0
If we subtract 1796 from 1880, we get 84.
Fetch the next digit (3) from the dividend, attach it to 84 and continue: 843 / 449

Let's proceed to step 6:
449 goes into 843 1 times with a remainder of 394.
Use 1 as the next digit of our solution. 
Result so far: 741.0
If we subtract 449 from 843, we get 394.
Fetch the next digit (7) from the dividend, attach it to 394 and continue: 3947 / 449

Let's proceed to step 7:
449 can be fit into 3947 8 times, resulting in a remainder of 355.
Write down 8 as next digit of the result. 
Result so far: 7418.0
The remainder is 355 after subtracting 3592 from 3947.
Fetch the next digit (5) from the dividend, attach it to 355 and continue: 3555 / 449

Advancing to step 8:
The number 449 fits into 3555 7 times, leaving a remainder of 412.
Write down 7 as next digit of the result. 
Result so far: 74187.0
If we take 3143 away from 3555, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 9:
449 can be fit into 4120 9 times, resulting in a remainder of 79.
The next digit of our result is 9. 
Result so far: 74187.9
Subtracting 4041 from 4120 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 10:
449 goes into 790 1 times with a remainder of 341.
The number 1 becomes the next digit in our result. 
Result so far: 74187.91
If we subtract 449 from 790, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

On to step 11:
449 can be fit into 3410 7 times, resulting in a remainder of 267.
Record the quotient 7 as the next digit in the result. 
Result so far: 74187.917
Subtracting 3143 from 3410 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 12:
If we divide 2670 by 449, we get 5 and a remainder of 425.
The next digit of our result is 5. 
Result so far: 74187.9175
Subtracting 2245 from 2670 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 13:
449 goes into 4250 9 times with a remainder of 209.
Put 9 as the next digit of the answer. 
Result so far: 74187.91759
Subtracting 4041 from 4250 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 14:
449 goes into 2090 4 times with a remainder of 294.
The next digit of our result is 4. 
Result so far: 74187.917594
Subtract 1796 from 2090 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 15:
If we divide 2940 by 449, we get 6 and a remainder of 246.
Use 6 as the next digit of our solution. 
Result so far: 74187.9175946
Subtracting 2694 from 2940 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 16:
The number 449 fits into 2460 5 times, leaving a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 74187.91759465
Deduct 2245 from 2460 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Our division results in 74187.91759465 with a remaining 2.15e-07.
