We divide 26059786 by 401
The aim is to understand the frequency of 401 in 26059786.

Advancing to step 1:
When dividing 2 by 401, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 401

Going ahead to step 2:
26 divided by 401 is 0 with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 401

Step 3:
When dividing 260 by 401, we get 0 with a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 260 to get 260.
Grab the next digit (5) from the dividend, add it to 260, then carry on: 2605 / 401

Moving on to step 4:
The number 401 fits into 2605 6 times, leaving a remainder of 199.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 199 after subtracting 2406 from 2605.
Bring next digit (9) of the dividend behind the 199 and repeat the process: 1999 / 401

On to step 5:
When dividing 1999 by 401, we get 4 with a remainder of 395.
Use 4 as the next digit of our solution. 
Result so far: 64.0
The remainder is 395 after subtracting 1604 from 1999.
Fetch the next digit (7) from the dividend, attach it to 395 and continue: 3957 / 401

Advancing to step 6:
401 can be fit into 3957 9 times, resulting in a remainder of 348.
Write down 9 as next digit of the result. 
Result so far: 649.0
Deduct 3609 from 3957 and we're left with 348.
Include the next digit (8) from the dividend after 348, then repeat: 3488 / 401

On to step 7:
The number 401 fits into 3488 8 times, leaving a remainder of 280.
Use 8 as the next digit of our solution. 
Result so far: 6498.0
If we take 3208 away from 3488, we end up with 280.
Fetch the next digit (6) from the dividend, attach it to 280 and continue: 2806 / 401

On to step 8:
If we divide 2806 by 401, we get 6 and a remainder of 400.
Write down 6 as next digit of the result. 
Result so far: 64986.0
The remainder is 400 after subtracting 2406 from 2806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 9:
If we divide 4000 by 401, we get 9 and a remainder of 391.
Use 9 as the next digit of our solution. 
Result so far: 64986.9
Subtracting 3609 from 4000 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 10:
401 can be fit into 3910 9 times, resulting in a remainder of 301.
Use 9 as the next digit of our solution. 
Result so far: 64986.99
If we take 3609 away from 3910, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

The final result is 64986.99 with a remainder of 0.301.
