50354941 ÷ 225 
The aim is to understand the frequency of 225 in 50354941.

On to step 1:
225 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 225

Let's proceed to step 2:
When dividing 50 by 225, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 225

Moving on to step 3:
225 goes into 503 2 times with a remainder of 53.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 53 after subtracting 450 from 503.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 225

Advancing to step 4:
225 can be fit into 535 2 times, resulting in a remainder of 85.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 450 from 535 and we're left with 85.
Include the next digit (4) from the dividend after 85, then repeat: 854 / 225

Step 5:
If we divide 854 by 225, we get 3 and a remainder of 179.
Use 3 as the next digit of our solution. 
Result so far: 223.0
If we take 675 away from 854, we end up with 179.
Bring next digit (9) of the dividend behind the 179 and repeat the process: 1799 / 225

Step 6:
If we divide 1799 by 225, we get 7 and a remainder of 224.
Put 7 as the next digit of the answer. 
Result so far: 2237.0
The remainder is 224 after subtracting 1575 from 1799.
Fetch the next digit (4) from the dividend, attach it to 224 and continue: 2244 / 225

Moving on to step 7:
225 goes into 2244 9 times with a remainder of 219.
Record the quotient 9 as the next digit in the result. 
Result so far: 22379.0
If we take 2025 away from 2244, we end up with 219.
Include the next digit (1) from the dividend after 219, then repeat: 2191 / 225

Let's proceed to step 8:
When dividing 2191 by 225, we get 9 with a remainder of 166.
Put 9 as the next digit of the answer. 
Result so far: 223799.0
If we take 2025 away from 2191, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 9:
225 goes into 1660 7 times with a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 223799.7
The remainder is 85 after subtracting 1575 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
850 divided by 225 is 3 with a remainder of 175.
Put 3 as the next digit of the answer. 
Result so far: 223799.73
If we take 675 away from 850, 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.

Step 11:
225 goes into 1750 7 times with a remainder of 175.
Record the quotient 7 as the next digit in the result. 
Result so far: 223799.737
Deduct 1575 from 1750 and we're left 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.

Moving on to step 12:
225 can be fit into 1750 7 times, resulting in a remainder of 175.
The number 7 becomes the next digit in our result. 
Result so far: 223799.7377
Subtracting 1575 from 1750 leaves us 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.

The final outcome is 223799.7377, with a leftover of 0.00175.
