We're dividing 40323832 by 225 
The aim is to understand the frequency of 225 in 40323832.

On to step 1:
The number 225 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 225

Step 2:
40 divided by 225 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 225

Going ahead to step 3:
403 divided by 225 is 1 with a remainder of 178.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 225 from 403 and we're left with 178.
Fetch the next digit (2) from the dividend, attach it to 178 and continue: 1782 / 225

On to step 4:
The number 225 fits into 1782 7 times, leaving a remainder of 207.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 1575 from 1782 to get 207.
Bring next digit (3) of the dividend behind the 207 and repeat the process: 2073 / 225

Step 5:
The number 225 fits into 2073 9 times, leaving a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
Subtract 2025 from 2073 to get 48.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 225

Moving on to step 6:
225 can be fit into 488 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 1792.0
Deduct 450 from 488 and we're left with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 225

Step 7:
When dividing 383 by 225, we get 1 with a remainder of 158.
The number 1 becomes the next digit in our result. 
Result so far: 17921.0
If we subtract 225 from 383, we get 158.
Take the next digit (2) from the dividend and append it to 158, then repeat: 1582 / 225

Going ahead to step 8:
When dividing 1582 by 225, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 179217.0
Subtracting 1575 from 1582 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
If we divide 70 by 225, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 179217.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
700 divided by 225 is 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 179217.03
If we subtract 675 from 700, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
225 goes into 250 1 times with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 179217.031
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
225 goes into 250 1 times with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 179217.0311
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 179217.0311 with a remainder of 0.00025.
