We look at the division of 20525360 by 425 
The aim is to understand the frequency of 425 in 20525360.

Step 1:
When dividing 2 by 425, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 425

Going ahead to step 2:
20 divided by 425 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 425

Going ahead to step 3:
When dividing 205 by 425, we get 0 with a remainder of 205.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 205 after subtracting 0 from 205.
Grab the next digit (2) from the dividend, add it to 205, then carry on: 2052 / 425

Step 4:
425 goes into 2052 4 times with a remainder of 352.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1700 from 2052 to get 352.
Append the next digit (5) from the dividend to 352 and continue with: 3525 / 425

On to step 5:
When dividing 3525 by 425, we get 8 with a remainder of 125.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtract 3400 from 3525 to get 125.
Append the next digit (3) from the dividend to 125 and continue with: 1253 / 425

Moving on to step 6:
425 goes into 1253 2 times with a remainder of 403.
The next digit of our result is 2. 
Result so far: 482.0
If we subtract 850 from 1253, we get 403.
Bring next digit (6) of the dividend behind the 403 and repeat the process: 4036 / 425

Let's proceed to step 7:
4036 divided by 425 is 9 with a remainder of 211.
The number 9 becomes the next digit in our result. 
Result so far: 4829.0
Subtracting 3825 from 4036 leaves us with 211.
Append the next digit (0) from the dividend to 211 and continue with: 2110 / 425

On to step 8:
When dividing 2110 by 425, we get 4 with a remainder of 410.
Use 4 as the next digit of our solution. 
Result so far: 48294.0
Subtracting 1700 from 2110 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 9:
425 goes into 4100 9 times with a remainder of 275.
Write down 9 as next digit of the result. 
Result so far: 48294.9
Deduct 3825 from 4100 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 10:
425 goes into 2750 6 times with a remainder of 200.
The number 6 becomes the next digit in our result. 
Result so far: 48294.96
If we take 2550 away from 2750, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
If we divide 2000 by 425, we get 4 and a remainder of 300.
The number 4 becomes the next digit in our result. 
Result so far: 48294.964
If we subtract 1700 from 2000, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 12:
If we divide 3000 by 425, we get 7 and a remainder of 25.
The next digit of our result is 7. 
Result so far: 48294.9647
The remainder is 25 after subtracting 2975 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
If we divide 250 by 425, we get 0 and a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 48294.9647
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 14:
The number 425 fits into 2500 5 times, leaving a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 48294.964705
If we subtract 2125 from 2500, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 15:
425 goes into 3750 8 times with a remainder of 350.
Write down 8 as next digit of the result. 
Result so far: 48294.9647058
If we take 3400 away from 3750, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 16:
425 goes into 3500 8 times with a remainder of 100.
Record the quotient 8 as the next digit in the result. 
Result so far: 48294.96470588
The remainder is 100 after subtracting 3400 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 48294.96470588 with a remainder of 1e-07.
