Let's divide 63559552 by 425
The aim is to understand the frequency of 425 in 63559552.

Moving on to step 1:
The number 425 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 425

Advancing to step 2:
425 can be fit into 63 0 times, resulting in a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 425

On to step 3:
When dividing 635 by 425, we get 1 with a remainder of 210.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 210 after subtracting 425 from 635.
Grab the next digit (5) from the dividend, add it to 210, then carry on: 2105 / 425

On to step 4:
The number 425 fits into 2105 4 times, leaving a remainder of 405.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 405 after subtracting 1700 from 2105.
Grab the next digit (9) from the dividend, add it to 405, then carry on: 4059 / 425

Going ahead to step 5:
425 can be fit into 4059 9 times, resulting in a remainder of 234.
Write down 9 as next digit of the result. 
Result so far: 149.0
If we subtract 3825 from 4059, we get 234.
Grab the next digit (5) from the dividend, add it to 234, then carry on: 2345 / 425

Step 6:
425 can be fit into 2345 5 times, resulting in a remainder of 220.
Use 5 as the next digit of our solution. 
Result so far: 1495.0
The remainder is 220 after subtracting 2125 from 2345.
Include the next digit (5) from the dividend after 220, then repeat: 2205 / 425

Going ahead to step 7:
If we divide 2205 by 425, we get 5 and a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 14955.0
Subtracting 2125 from 2205 leaves us with 80.
Append the next digit (2) from the dividend to 80 and continue with: 802 / 425

Moving on to step 8:
802 divided by 425 is 1 with a remainder of 377.
Record the quotient 1 as the next digit in the result. 
Result so far: 149551.0
If we subtract 425 from 802, we get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 9:
425 goes into 3770 8 times with a remainder of 370.
The next digit of our result is 8. 
Result so far: 149551.8
Subtract 3400 from 3770 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 10:
The number 425 fits into 3700 8 times, leaving a remainder of 300.
The number 8 becomes the next digit in our result. 
Result so far: 149551.88
Subtracting 3400 from 3700 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 149551.88 and a remainder of 0.3.
