1010469 ÷ 225 
The aim is to understand the frequency of 225 in 1010469.

Let's proceed to step 1:
If we divide 1 by 225, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 225

Let's proceed to step 2:
225 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 225

Step 3:
The number 225 fits into 101 0 times, leaving a remainder of 101.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 101 leaves us with 101.
Take the next digit (0) from the dividend and append it to 101, then repeat: 1010 / 225

Step 4:
When dividing 1010 by 225, we get 4 with a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 900 away from 1010, we end up with 110.
Bring next digit (4) of the dividend behind the 110 and repeat the process: 1104 / 225

On to step 5:
If we divide 1104 by 225, we get 4 and a remainder of 204.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtracting 900 from 1104 leaves us with 204.
Bring next digit (6) of the dividend behind the 204 and repeat the process: 2046 / 225

Advancing to step 6:
If we divide 2046 by 225, we get 9 and a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 449.0
If we take 2025 away from 2046, we end up with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 225

Let's proceed to step 7:
If we divide 219 by 225, we get 0 and a remainder of 219.
Put 0 as the next digit of the answer. 
Result so far: 4490.0
Subtract 0 from 219 to get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Going ahead to step 8:
The number 225 fits into 2190 9 times, leaving a remainder of 165.
Write down 9 as next digit of the result. 
Result so far: 4490.9
If we take 2025 away from 2190, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 9:
The number 225 fits into 1650 7 times, leaving a remainder of 75.
Put 7 as the next digit of the answer. 
Result so far: 4490.97
Deduct 1575 from 1650 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
750 divided by 225 is 3 with a remainder of 75.
The number 3 becomes the next digit in our result. 
Result so far: 4490.973
The remainder is 75 after subtracting 675 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
750 divided by 225 is 3 with a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 4490.9733
If we subtract 675 from 750, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final result is 4490.9733 with a remainder of 0.00075.
