We look at the division of 98645958 by 225 
The aim is to understand the frequency of 225 in 98645958.

Advancing to step 1:
225 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 225

Step 2:
98 divided by 225 is 0 with a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Append the next digit (6) from the dividend to 98 and continue with: 986 / 225

On to step 3:
225 goes into 986 4 times with a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 900 from 986 leaves us with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 225

Going ahead to step 4:
225 goes into 864 3 times with a remainder of 189.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 675 from 864, we get 189.
Append the next digit (5) from the dividend to 189 and continue with: 1895 / 225

Step 5:
The number 225 fits into 1895 8 times, leaving a remainder of 95.
Write down 8 as next digit of the result. 
Result so far: 438.0
If we subtract 1800 from 1895, we get 95.
Include the next digit (9) from the dividend after 95, then repeat: 959 / 225

On to step 6:
225 goes into 959 4 times with a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 4384.0
If we subtract 900 from 959, we get 59.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 225

Going ahead to step 7:
When dividing 595 by 225, we get 2 with a remainder of 145.
Write down 2 as next digit of the result. 
Result so far: 43842.0
The remainder is 145 after subtracting 450 from 595.
Bring next digit (8) of the dividend behind the 145 and repeat the process: 1458 / 225

Advancing to step 8:
225 can be fit into 1458 6 times, resulting in a remainder of 108.
The next digit of our result is 6. 
Result so far: 438426.0
If we subtract 1350 from 1458, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 9:
If we divide 1080 by 225, we get 4 and a remainder of 180.
The next digit of our result is 4. 
Result so far: 438426.4
If we subtract 900 from 1080, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 10:
1800 divided by 225 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 438426.48
If we take 1800 away from 1800, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 225 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 438426.48
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
When dividing 0 by 225, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 438426.48
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 438426.48 with a remaining 0.0.
