81140237 divided by 449 
The aim is to understand the frequency of 449 in 81140237.

On to step 1:
If we divide 8 by 449, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 449

Advancing to step 2:
449 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 449

Advancing to step 3:
If we divide 811 by 449, we get 1 and a remainder of 362.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 449 from 811 to get 362.
Bring next digit (4) of the dividend behind the 362 and repeat the process: 3624 / 449

Step 4:
The number 449 fits into 3624 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 3592 from 3624 to get 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 449

On to step 5:
The number 449 fits into 320 0 times, leaving a remainder of 320.
The next digit of our result is 0. 
Result so far: 180.0
If we take 0 away from 320, we end up with 320.
Fetch the next digit (2) from the dividend, attach it to 320 and continue: 3202 / 449

Step 6:
3202 divided by 449 is 7 with a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 1807.0
The remainder is 59 after subtracting 3143 from 3202.
Bring next digit (3) of the dividend behind the 59 and repeat the process: 593 / 449

Step 7:
When dividing 593 by 449, we get 1 with a remainder of 144.
Put 1 as the next digit of the answer. 
Result so far: 18071.0
Deduct 449 from 593 and we're left with 144.
Fetch the next digit (7) from the dividend, attach it to 144 and continue: 1447 / 449

Moving on to step 8:
449 goes into 1447 3 times with a remainder of 100.
Record the quotient 3 as the next digit in the result. 
Result so far: 180713.0
The remainder is 100 after subtracting 1347 from 1447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 9:
449 can be fit into 1000 2 times, resulting in a remainder of 102.
Put 2 as the next digit of the answer. 
Result so far: 180713.2
If we subtract 898 from 1000, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 10:
1020 divided by 449 is 2 with a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 180713.22
If we subtract 898 from 1020, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

After the division, we end up with 180713.22 and a remainder of 0.122.
