We're dividing 31821662 by 225 
The aim is to understand the frequency of 225 in 31821662.

Moving on to step 1:
If we divide 3 by 225, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 225

Step 2:
If we divide 31 by 225, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 225

Step 3:
318 divided by 225 is 1 with a remainder of 93.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 225 from 318 and we're left with 93.
Take the next digit (2) from the dividend and append it to 93, then repeat: 932 / 225

Step 4:
The number 225 fits into 932 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 900 from 932 leaves us with 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 225

Moving on to step 5:
225 goes into 321 1 times with a remainder of 96.
Put 1 as the next digit of the answer. 
Result so far: 141.0
Subtracting 225 from 321 leaves us with 96.
Bring next digit (6) of the dividend behind the 96 and repeat the process: 966 / 225

Advancing to step 6:
966 divided by 225 is 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 1414.0
Subtract 900 from 966 to get 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 225

Advancing to step 7:
The number 225 fits into 666 2 times, leaving a remainder of 216.
Put 2 as the next digit of the answer. 
Result so far: 14142.0
If we subtract 450 from 666, we get 216.
Bring next digit (2) of the dividend behind the 216 and repeat the process: 2162 / 225

Step 8:
The number 225 fits into 2162 9 times, leaving a remainder of 137.
Put 9 as the next digit of the answer. 
Result so far: 141429.0
Deduct 2025 from 2162 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 9:
The number 225 fits into 1370 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 141429.6
If we subtract 1350 from 1370, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
When dividing 200 by 225, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 141429.6
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
2000 divided by 225 is 8 with a remainder of 200.
The number 8 becomes the next digit in our result. 
Result so far: 141429.608
Subtracting 1800 from 2000 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
2000 divided by 225 is 8 with a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 141429.6088
If we take 1800 away from 2000, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 141429.6088 with a balance of 0.002.
