We're dividing 25865146 by 418 
The aim is to understand the frequency of 418 in 25865146.

Moving on to step 1:
If we divide 2 by 418, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 418

Going ahead to step 2:
418 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 418

Moving on to step 3:
418 goes into 258 0 times with a remainder of 258.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 258 to get 258.
Include the next digit (6) from the dividend after 258, then repeat: 2586 / 418

Going ahead to step 4:
418 can be fit into 2586 6 times, resulting in a remainder of 78.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 78 after subtracting 2508 from 2586.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 418

Step 5:
785 divided by 418 is 1 with a remainder of 367.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
If we take 418 away from 785, we end up with 367.
Include the next digit (1) from the dividend after 367, then repeat: 3671 / 418

Advancing to step 6:
3671 divided by 418 is 8 with a remainder of 327.
Use 8 as the next digit of our solution. 
Result so far: 618.0
Deduct 3344 from 3671 and we're left with 327.
Append the next digit (4) from the dividend to 327 and continue with: 3274 / 418

Going ahead to step 7:
3274 divided by 418 is 7 with a remainder of 348.
Use 7 as the next digit of our solution. 
Result so far: 6187.0
If we take 2926 away from 3274, we end up with 348.
Fetch the next digit (6) from the dividend, attach it to 348 and continue: 3486 / 418

Let's proceed to step 8:
418 can be fit into 3486 8 times, resulting in a remainder of 142.
The next digit of our result is 8. 
Result so far: 61878.0
Deduct 3344 from 3486 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 9:
1420 divided by 418 is 3 with a remainder of 166.
The number 3 becomes the next digit in our result. 
Result so far: 61878.3
If we subtract 1254 from 1420, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 10:
1660 divided by 418 is 3 with a remainder of 406.
Record the quotient 3 as the next digit in the result. 
Result so far: 61878.33
If we take 1254 away from 1660, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

The final outcome is 61878.33, with a leftover of 0.406.
