Let's divide 13390396 by 497
The aim is to understand the frequency of 497 in 13390396.

On to step 1:
497 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
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 / 497

Let's proceed to step 2:
497 can be fit into 13 0 times, resulting in a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 497

Going ahead to step 3:
497 goes into 133 0 times with a remainder of 133.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 133 leaves us with 133.
Include the next digit (9) from the dividend after 133, then repeat: 1339 / 497

Moving on to step 4:
If we divide 1339 by 497, we get 2 and a remainder of 345.
The next digit of our result is 2. 
Result so far: 2.0
If we take 994 away from 1339, we end up with 345.
Bring next digit (0) of the dividend behind the 345 and repeat the process: 3450 / 497

Step 5:
497 can be fit into 3450 6 times, resulting in a remainder of 468.
Use 6 as the next digit of our solution. 
Result so far: 26.0
The remainder is 468 after subtracting 2982 from 3450.
Take the next digit (3) from the dividend and append it to 468, then repeat: 4683 / 497

Step 6:
If we divide 4683 by 497, we get 9 and a remainder of 210.
The next digit of our result is 9. 
Result so far: 269.0
Subtract 4473 from 4683 to get 210.
Include the next digit (9) from the dividend after 210, then repeat: 2109 / 497

Let's proceed to step 7:
The number 497 fits into 2109 4 times, leaving a remainder of 121.
Write down 4 as next digit of the result. 
Result so far: 2694.0
If we take 1988 away from 2109, we end up with 121.
Append the next digit (6) from the dividend to 121 and continue with: 1216 / 497

Step 8:
1216 divided by 497 is 2 with a remainder of 222.
The next digit of our result is 2. 
Result so far: 26942.0
The remainder is 222 after subtracting 994 from 1216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 9:
The number 497 fits into 2220 4 times, leaving a remainder of 232.
Record the quotient 4 as the next digit in the result. 
Result so far: 26942.4
The remainder is 232 after subtracting 1988 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 10:
When dividing 2320 by 497, we get 4 with a remainder of 332.
The next digit of our result is 4. 
Result so far: 26942.44
The remainder is 332 after subtracting 1988 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The final outcome is 26942.44, with a leftover of 0.332.
