We look at the division of 25991693 by 413 
The aim is to understand the frequency of 413 in 25991693.

Let's proceed to step 1:
When dividing 2 by 413, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 413

Advancing to step 2:
The number 413 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 413

Let's proceed to step 3:
259 divided by 413 is 0 with a remainder of 259.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 259 to get 259.
Grab the next digit (9) from the dividend, add it to 259, then carry on: 2599 / 413

Step 4:
413 can be fit into 2599 6 times, resulting in a remainder of 121.
The next digit of our result is 6. 
Result so far: 6.0
If we take 2478 away from 2599, we end up with 121.
Take the next digit (1) from the dividend and append it to 121, then repeat: 1211 / 413

Advancing to step 5:
When dividing 1211 by 413, we get 2 with a remainder of 385.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Subtract 826 from 1211 to get 385.
Bring next digit (6) of the dividend behind the 385 and repeat the process: 3856 / 413

Let's proceed to step 6:
413 can be fit into 3856 9 times, resulting in a remainder of 139.
The number 9 becomes the next digit in our result. 
Result so far: 629.0
Subtract 3717 from 3856 to get 139.
Take the next digit (9) from the dividend and append it to 139, then repeat: 1399 / 413

Moving on to step 7:
The number 413 fits into 1399 3 times, leaving a remainder of 160.
The next digit of our result is 3. 
Result so far: 6293.0
Subtracting 1239 from 1399 leaves us with 160.
Bring next digit (3) of the dividend behind the 160 and repeat the process: 1603 / 413

Moving on to step 8:
1603 divided by 413 is 3 with a remainder of 364.
The next digit of our result is 3. 
Result so far: 62933.0
If we subtract 1239 from 1603, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 9:
The number 413 fits into 3640 8 times, leaving a remainder of 336.
Use 8 as the next digit of our solution. 
Result so far: 62933.8
Subtract 3304 from 3640 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 10:
When dividing 3360 by 413, we get 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 62933.88
Subtract 3304 from 3360 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 62933.88, with a leftover of 0.056.
