Let's divide 18435850 by 440
The aim is to understand the frequency of 440 in 18435850.

On to step 1:
When dividing 1 by 440, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 440

Moving on to step 2:
The number 440 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 440

Step 3:
440 can be fit into 184 0 times, resulting in a remainder of 184.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 184 leaves us with 184.
Grab the next digit (3) from the dividend, add it to 184, then carry on: 1843 / 440

Advancing to step 4:
When dividing 1843 by 440, we get 4 with a remainder of 83.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 83 after subtracting 1760 from 1843.
Bring next digit (5) of the dividend behind the 83 and repeat the process: 835 / 440

Advancing to step 5:
440 goes into 835 1 times with a remainder of 395.
Put 1 as the next digit of the answer. 
Result so far: 41.0
The remainder is 395 after subtracting 440 from 835.
Include the next digit (8) from the dividend after 395, then repeat: 3958 / 440

On to step 6:
440 goes into 3958 8 times with a remainder of 438.
The next digit of our result is 8. 
Result so far: 418.0
If we subtract 3520 from 3958, we get 438.
Include the next digit (5) from the dividend after 438, then repeat: 4385 / 440

Let's proceed to step 7:
4385 divided by 440 is 9 with a remainder of 425.
The number 9 becomes the next digit in our result. 
Result so far: 4189.0
If we take 3960 away from 4385, we end up with 425.
Grab the next digit (0) from the dividend, add it to 425, then carry on: 4250 / 440

Moving on to step 8:
The number 440 fits into 4250 9 times, leaving a remainder of 290.
Use 9 as the next digit of our solution. 
Result so far: 41899.0
Subtracting 3960 from 4250 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 9:
440 goes into 2900 6 times with a remainder of 260.
Write down 6 as next digit of the result. 
Result so far: 41899.6
The remainder is 260 after subtracting 2640 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 10:
The number 440 fits into 2600 5 times, leaving a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 41899.65
Subtracting 2200 from 2600 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 11:
4000 divided by 440 is 9 with a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 41899.659
Deduct 3960 from 4000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
440 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 41899.659
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 13:
If we divide 4000 by 440, we get 9 and a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 41899.65909
Deduct 3960 from 4000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
The number 440 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 41899.65909
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 15:
When dividing 4000 by 440, we get 9 with a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 41899.6590909
If we subtract 3960 from 4000, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
440 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 41899.6590909
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 41899.6590909, with a leftover of 4e-07.
