47042400 divided by 449 
The aim is to understand the frequency of 449 in 47042400.

On to step 1:
If we divide 4 by 449, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 449

Advancing to step 2:
449 goes into 47 0 times with a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 449

On to step 3:
The number 449 fits into 470 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 449 from 470 and we're left with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 449

Step 4:
If we divide 214 by 449, we get 0 and a remainder of 214.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 214 leaves us with 214.
Take the next digit (2) from the dividend and append it to 214, then repeat: 2142 / 449

Step 5:
If we divide 2142 by 449, we get 4 and a remainder of 346.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Deduct 1796 from 2142 and we're left with 346.
Include the next digit (4) from the dividend after 346, then repeat: 3464 / 449

Step 6:
If we divide 3464 by 449, we get 7 and a remainder of 321.
Put 7 as the next digit of the answer. 
Result so far: 1047.0
Deduct 3143 from 3464 and we're left with 321.
Include the next digit (0) from the dividend after 321, then repeat: 3210 / 449

Let's proceed to step 7:
If we divide 3210 by 449, we get 7 and a remainder of 67.
The next digit of our result is 7. 
Result so far: 10477.0
Subtracting 3143 from 3210 leaves us with 67.
Bring next digit (0) of the dividend behind the 67 and repeat the process: 670 / 449

Step 8:
670 divided by 449 is 1 with a remainder of 221.
Use 1 as the next digit of our solution. 
Result so far: 104771.0
If we take 449 away from 670, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 9:
2210 divided by 449 is 4 with a remainder of 414.
The number 4 becomes the next digit in our result. 
Result so far: 104771.4
Deduct 1796 from 2210 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 10:
When dividing 4140 by 449, we get 9 with a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 104771.49
If we subtract 4041 from 4140, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 11:
When dividing 990 by 449, we get 2 with a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 104771.492
Subtracting 898 from 990 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 12:
449 can be fit into 920 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 104771.4922
If we subtract 898 from 920, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 104771.4922 and a remainder of 0.00022.
