We look at the division of 42934842 by 225 
The aim is to understand the frequency of 225 in 42934842.

Let's proceed to step 1:
When dividing 4 by 225, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 225

Step 2:
If we divide 42 by 225, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 225

Going ahead to step 3:
225 can be fit into 429 1 times, resulting in a remainder of 204.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 225 from 429 leaves us with 204.
Fetch the next digit (3) from the dividend, attach it to 204 and continue: 2043 / 225

Going ahead to step 4:
The number 225 fits into 2043 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 2025 from 2043 to get 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 225

Step 5:
If we divide 184 by 225, we get 0 and a remainder of 184.
Put 0 as the next digit of the answer. 
Result so far: 190.0
Deduct 0 from 184 and we're left with 184.
Grab the next digit (8) from the dividend, add it to 184, then carry on: 1848 / 225

Going ahead to step 6:
The number 225 fits into 1848 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 1908.0
If we subtract 1800 from 1848, we get 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 225

Let's proceed to step 7:
When dividing 484 by 225, we get 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 19082.0
Subtracting 450 from 484 leaves us with 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 225

Step 8:
If we divide 342 by 225, we get 1 and a remainder of 117.
Write down 1 as next digit of the result. 
Result so far: 190821.0
Subtract 225 from 342 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
225 can be fit into 1170 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 190821.5
Deduct 1125 from 1170 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
450 divided by 225 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 190821.52
Deduct 450 from 450 and we're left 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 11:
225 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 190821.52
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
0 divided by 225 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 190821.52
Deduct 0 from 0 and we're left 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.

Our division results in 190821.52 with a remaining 0.0.
