8806245 ÷ 225 
The aim is to understand the frequency of 225 in 8806245.

Going ahead to step 1:
The number 225 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 225

On to step 2:
When dividing 88 by 225, we get 0 with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Take the next digit (0) from the dividend and append it to 88, then repeat: 880 / 225

Moving on to step 3:
When dividing 880 by 225, we get 3 with a remainder of 205.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 675 from 880 leaves us with 205.
Include the next digit (6) from the dividend after 205, then repeat: 2056 / 225

Step 4:
The number 225 fits into 2056 9 times, leaving a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 2025 away from 2056, we end up with 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 225

Moving on to step 5:
225 goes into 312 1 times with a remainder of 87.
Record the quotient 1 as the next digit in the result. 
Result so far: 391.0
If we take 225 away from 312, we end up with 87.
Grab the next digit (4) from the dividend, add it to 87, then carry on: 874 / 225

Step 6:
225 can be fit into 874 3 times, resulting in a remainder of 199.
Use 3 as the next digit of our solution. 
Result so far: 3913.0
If we take 675 away from 874, we end up with 199.
Grab the next digit (5) from the dividend, add it to 199, then carry on: 1995 / 225

Going ahead to step 7:
225 can be fit into 1995 8 times, resulting in a remainder of 195.
Put 8 as the next digit of the answer. 
Result so far: 39138.0
Subtracting 1800 from 1995 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 8:
If we divide 1950 by 225, we get 8 and a remainder of 150.
The number 8 becomes the next digit in our result. 
Result so far: 39138.8
If we subtract 1800 from 1950, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 9:
225 goes into 1500 6 times with a remainder of 150.
The number 6 becomes the next digit in our result. 
Result so far: 39138.86
If we subtract 1350 from 1500, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
225 goes into 1500 6 times with a remainder of 150.
Record the quotient 6 as the next digit in the result. 
Result so far: 39138.866
If we take 1350 away from 1500, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The quotient of the division is 39138.866, and the remainder is 0.015.
