We look at the division of 25924444 by 524 
The aim is to understand the frequency of 524 in 25924444.

Advancing to step 1:
When dividing 2 by 524, 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.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 524

Going ahead to step 2:
524 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 524

Advancing to step 3:
When dividing 259 by 524, we get 0 with a remainder of 259.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 259, we get 259.
Grab the next digit (2) from the dividend, add it to 259, then carry on: 2592 / 524

Advancing to step 4:
If we divide 2592 by 524, we get 4 and a remainder of 496.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 496 after subtracting 2096 from 2592.
Include the next digit (4) from the dividend after 496, then repeat: 4964 / 524

Advancing to step 5:
4964 divided by 524 is 9 with a remainder of 248.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 248 after subtracting 4716 from 4964.
Take the next digit (4) from the dividend and append it to 248, then repeat: 2484 / 524

Let's proceed to step 6:
The number 524 fits into 2484 4 times, leaving a remainder of 388.
Write down 4 as next digit of the result. 
Result so far: 494.0
If we take 2096 away from 2484, we end up with 388.
Include the next digit (4) from the dividend after 388, then repeat: 3884 / 524

Let's proceed to step 7:
If we divide 3884 by 524, we get 7 and a remainder of 216.
Record the quotient 7 as the next digit in the result. 
Result so far: 4947.0
Subtracting 3668 from 3884 leaves us with 216.
Fetch the next digit (4) from the dividend, attach it to 216 and continue: 2164 / 524

Moving on to step 8:
When dividing 2164 by 524, we get 4 with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 49474.0
If we take 2096 away from 2164, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
When dividing 680 by 524, we get 1 with a remainder of 156.
The next digit of our result is 1. 
Result so far: 49474.1
Subtracting 524 from 680 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 10:
If we divide 1560 by 524, we get 2 and a remainder of 512.
The next digit of our result is 2. 
Result so far: 49474.12
Deduct 1048 from 1560 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 11:
When dividing 5120 by 524, we get 9 with a remainder of 404.
Put 9 as the next digit of the answer. 
Result so far: 49474.129
Subtract 4716 from 5120 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 12:
524 can be fit into 4040 7 times, resulting in a remainder of 372.
The next digit of our result is 7. 
Result so far: 49474.1297
Subtracting 3668 from 4040 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 13:
3720 divided by 524 is 7 with a remainder of 52.
The next digit of our result is 7. 
Result so far: 49474.12977
The remainder is 52 after subtracting 3668 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 49474.12977 with a remaining 5.2e-05.
