We're dividing 65317841 by 225 
The aim is to understand the frequency of 225 in 65317841.

Going ahead to step 1:
The number 225 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 225

On to step 2:
The number 225 fits into 65 0 times, leaving a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Fetch the next digit (3) from the dividend, attach it to 65 and continue: 653 / 225

Step 3:
When dividing 653 by 225, we get 2 with a remainder of 203.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 203 after subtracting 450 from 653.
Fetch the next digit (1) from the dividend, attach it to 203 and continue: 2031 / 225

Step 4:
225 goes into 2031 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 2025 away from 2031, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 225

Moving on to step 5:
The number 225 fits into 67 0 times, leaving a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 290.0
Deduct 0 from 67 and we're left with 67.
Include the next digit (8) from the dividend after 67, then repeat: 678 / 225

Moving on to step 6:
If we divide 678 by 225, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 2903.0
Deduct 675 from 678 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 225

On to step 7:
225 goes into 34 0 times with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 29030.0
Deduct 0 from 34 and we're left with 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 225

Advancing to step 8:
225 goes into 341 1 times with a remainder of 116.
Put 1 as the next digit of the answer. 
Result so far: 290301.0
Subtract 225 from 341 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 9:
1160 divided by 225 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 290301.5
Deduct 1125 from 1160 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
225 can be fit into 350 1 times, resulting in a remainder of 125.
Use 1 as the next digit of our solution. 
Result so far: 290301.51
If we subtract 225 from 350, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
If we divide 1250 by 225, we get 5 and a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 290301.515
If we take 1125 away from 1250, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 12:
If we divide 1250 by 225, we get 5 and a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 290301.5155
If we subtract 1125 from 1250, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Our division results in 290301.5155 with a remaining 0.00125.
