13415582 ÷ 490 
The aim is to understand the frequency of 490 in 13415582.

Going ahead to step 1:
When dividing 1 by 490, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 490

Let's proceed to step 2:
490 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 490

Going ahead to step 3:
490 can be fit into 134 0 times, resulting in a remainder of 134.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 134 to get 134.
Take the next digit (1) from the dividend and append it to 134, then repeat: 1341 / 490

On to step 4:
The number 490 fits into 1341 2 times, leaving a remainder of 361.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 980 from 1341 and we're left with 361.
Fetch the next digit (5) from the dividend, attach it to 361 and continue: 3615 / 490

Going ahead to step 5:
When dividing 3615 by 490, we get 7 with a remainder of 185.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
The remainder is 185 after subtracting 3430 from 3615.
Take the next digit (5) from the dividend and append it to 185, then repeat: 1855 / 490

Going ahead to step 6:
When dividing 1855 by 490, we get 3 with a remainder of 385.
The next digit of our result is 3. 
Result so far: 273.0
Deduct 1470 from 1855 and we're left with 385.
Fetch the next digit (8) from the dividend, attach it to 385 and continue: 3858 / 490

On to step 7:
3858 divided by 490 is 7 with a remainder of 428.
The next digit of our result is 7. 
Result so far: 2737.0
Subtracting 3430 from 3858 leaves us with 428.
Append the next digit (2) from the dividend to 428 and continue with: 4282 / 490

Step 8:
490 goes into 4282 8 times with a remainder of 362.
The number 8 becomes the next digit in our result. 
Result so far: 27378.0
The remainder is 362 after subtracting 3920 from 4282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 9:
490 can be fit into 3620 7 times, resulting in a remainder of 190.
Put 7 as the next digit of the answer. 
Result so far: 27378.7
The remainder is 190 after subtracting 3430 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
490 can be fit into 1900 3 times, resulting in a remainder of 430.
Put 3 as the next digit of the answer. 
Result so far: 27378.73
If we take 1470 away from 1900, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 11:
The number 490 fits into 4300 8 times, leaving a remainder of 380.
The number 8 becomes the next digit in our result. 
Result so far: 27378.738
If we subtract 3920 from 4300, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 12:
If we divide 3800 by 490, we get 7 and a remainder of 370.
Write down 7 as next digit of the result. 
Result so far: 27378.7387
If we subtract 3430 from 3800, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 13:
When dividing 3700 by 490, we get 7 with a remainder of 270.
Put 7 as the next digit of the answer. 
Result so far: 27378.73877
Subtracting 3430 from 3700 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final outcome is 27378.73877, with a leftover of 0.00027.
