We look at the division of 34568149 by 225 
The aim is to understand the frequency of 225 in 34568149.

Going ahead to step 1:
The number 225 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 225

Moving on to step 2:
When dividing 34 by 225, we get 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 225

Let's proceed to step 3:
345 divided by 225 is 1 with a remainder of 120.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 120 after subtracting 225 from 345.
Append the next digit (6) from the dividend to 120 and continue with: 1206 / 225

Step 4:
The number 225 fits into 1206 5 times, leaving a remainder of 81.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 1125 from 1206 leaves us with 81.
Grab the next digit (8) from the dividend, add it to 81, then carry on: 818 / 225

Step 5:
If we divide 818 by 225, we get 3 and a remainder of 143.
The next digit of our result is 3. 
Result so far: 153.0
Deduct 675 from 818 and we're left with 143.
Grab the next digit (1) from the dividend, add it to 143, then carry on: 1431 / 225

Going ahead to step 6:
When dividing 1431 by 225, we get 6 with a remainder of 81.
Put 6 as the next digit of the answer. 
Result so far: 1536.0
Subtract 1350 from 1431 to get 81.
Take the next digit (4) from the dividend and append it to 81, then repeat: 814 / 225

Advancing to step 7:
225 goes into 814 3 times with a remainder of 139.
Use 3 as the next digit of our solution. 
Result so far: 15363.0
Subtracting 675 from 814 leaves us with 139.
Append the next digit (9) from the dividend to 139 and continue with: 1399 / 225

Going ahead to step 8:
When dividing 1399 by 225, we get 6 with a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 153636.0
Deduct 1350 from 1399 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 9:
490 divided by 225 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 153636.2
If we take 450 away from 490, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 225 is 1 with a remainder of 175.
Use 1 as the next digit of our solution. 
Result so far: 153636.21
If we subtract 225 from 400, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 11:
If we divide 1750 by 225, we get 7 and a remainder of 175.
Record the quotient 7 as the next digit in the result. 
Result so far: 153636.217
If we subtract 1575 from 1750, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 12:
If we divide 1750 by 225, we get 7 and a remainder of 175.
The next digit of our result is 7. 
Result so far: 153636.2177
If we take 1575 away from 1750, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

After the division, we end up with 153636.2177 and a remainder of 0.00175.
