66767262 ÷ 225 
The aim is to understand the frequency of 225 in 66767262.

Step 1:
225 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 225

Advancing to step 2:
The number 225 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 225

Let's proceed to step 3:
If we divide 667 by 225, we get 2 and a remainder of 217.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 450 from 667, we get 217.
Grab the next digit (6) from the dividend, add it to 217, then carry on: 2176 / 225

Let's proceed to step 4:
The number 225 fits into 2176 9 times, leaving a remainder of 151.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we take 2025 away from 2176, we end up with 151.
Fetch the next digit (7) from the dividend, attach it to 151 and continue: 1517 / 225

Step 5:
If we divide 1517 by 225, we get 6 and a remainder of 167.
Use 6 as the next digit of our solution. 
Result so far: 296.0
Subtracting 1350 from 1517 leaves us with 167.
Append the next digit (2) from the dividend to 167 and continue with: 1672 / 225

On to step 6:
1672 divided by 225 is 7 with a remainder of 97.
Write down 7 as next digit of the result. 
Result so far: 2967.0
Subtracting 1575 from 1672 leaves us with 97.
Grab the next digit (6) from the dividend, add it to 97, then carry on: 976 / 225

Advancing to step 7:
If we divide 976 by 225, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 29674.0
Deduct 900 from 976 and we're left with 76.
Bring next digit (2) of the dividend behind the 76 and repeat the process: 762 / 225

Going ahead to step 8:
225 can be fit into 762 3 times, resulting in a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 296743.0
If we take 675 away from 762, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 9:
When dividing 870 by 225, we get 3 with a remainder of 195.
Record the quotient 3 as the next digit in the result. 
Result so far: 296743.3
Deduct 675 from 870 and we're left 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.

Step 10:
225 goes into 1950 8 times with a remainder of 150.
Put 8 as the next digit of the answer. 
Result so far: 296743.38
The remainder is 150 after subtracting 1800 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 11:
225 can be fit into 1500 6 times, resulting in a remainder of 150.
The number 6 becomes the next digit in our result. 
Result so far: 296743.386
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.

Let's proceed to step 12:
225 can be fit into 1500 6 times, resulting in a remainder of 150.
Record the quotient 6 as the next digit in the result. 
Result so far: 296743.3866
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.

Our division results in 296743.3866 with a remaining 0.0015.
