We look at the division of 25337584 by 425 
The aim is to understand the frequency of 425 in 25337584.

Advancing to 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
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 425

Moving on to step 2:
When dividing 25 by 425, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 425

Step 3:
When dividing 253 by 425, we get 0 with a remainder of 253.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 253 leaves us with 253.
Take the next digit (3) from the dividend and append it to 253, then repeat: 2533 / 425

Going ahead to step 4:
When dividing 2533 by 425, we get 5 with a remainder of 408.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 408 after subtracting 2125 from 2533.
Include the next digit (7) from the dividend after 408, then repeat: 4087 / 425

Step 5:
4087 divided by 425 is 9 with a remainder of 262.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Subtracting 3825 from 4087 leaves us with 262.
Include the next digit (5) from the dividend after 262, then repeat: 2625 / 425

Advancing to step 6:
If we divide 2625 by 425, we get 6 and a remainder of 75.
Record the quotient 6 as the next digit in the result. 
Result so far: 596.0
If we subtract 2550 from 2625, we get 75.
Fetch the next digit (8) from the dividend, attach it to 75 and continue: 758 / 425

Let's proceed to step 7:
If we divide 758 by 425, we get 1 and a remainder of 333.
The next digit of our result is 1. 
Result so far: 5961.0
Subtracting 425 from 758 leaves us with 333.
Fetch the next digit (4) from the dividend, attach it to 333 and continue: 3334 / 425

On to step 8:
If we divide 3334 by 425, we get 7 and a remainder of 359.
Record the quotient 7 as the next digit in the result. 
Result so far: 59617.0
Subtracting 2975 from 3334 leaves us with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 9:
425 goes into 3590 8 times with a remainder of 190.
Write down 8 as next digit of the result. 
Result so far: 59617.8
Deduct 3400 from 3590 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 10:
The number 425 fits into 1900 4 times, leaving a remainder of 200.
Record the quotient 4 as the next digit in the result. 
Result so far: 59617.84
Deduct 1700 from 1900 and we're left 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:
When dividing 2000 by 425, we get 4 with a remainder of 300.
The next digit of our result is 4. 
Result so far: 59617.844
Subtract 1700 from 2000 to 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.

The quotient of the division is 59617.844, and the remainder is 0.03.
