Let's divide 3518990 by 459
The aim is to understand the frequency of 459 in 3518990.

Advancing to step 1:
When dividing 3 by 459, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 459

Going ahead to step 2:
The number 459 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 459

Let's proceed to step 3:
The number 459 fits into 351 0 times, leaving a remainder of 351.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 351 after subtracting 0 from 351.
Include the next digit (8) from the dividend after 351, then repeat: 3518 / 459

Going ahead to step 4:
459 goes into 3518 7 times with a remainder of 305.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 305 after subtracting 3213 from 3518.
Append the next digit (9) from the dividend to 305 and continue with: 3059 / 459

On to step 5:
The number 459 fits into 3059 6 times, leaving a remainder of 305.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Subtract 2754 from 3059 to get 305.
Grab the next digit (9) from the dividend, add it to 305, then carry on: 3059 / 459

Step 6:
3059 divided by 459 is 6 with a remainder of 305.
The number 6 becomes the next digit in our result. 
Result so far: 766.0
If we take 2754 away from 3059, we end up with 305.
Grab the next digit (0) from the dividend, add it to 305, then carry on: 3050 / 459

Advancing to step 7:
When dividing 3050 by 459, we get 6 with a remainder of 296.
Write down 6 as next digit of the result. 
Result so far: 7666.0
Deduct 2754 from 3050 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 8:
459 goes into 2960 6 times with a remainder of 206.
The number 6 becomes the next digit in our result. 
Result so far: 7666.6
If we subtract 2754 from 2960, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 9:
459 can be fit into 2060 4 times, resulting in a remainder of 224.
Use 4 as the next digit of our solution. 
Result so far: 7666.64
Deduct 1836 from 2060 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 10:
459 goes into 2240 4 times with a remainder of 404.
The next digit of our result is 4. 
Result so far: 7666.644
Deduct 1836 from 2240 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

The final result is 7666.644 with a remainder of 0.0404.
