Let's divide 40187360 by 225
The aim is to understand the frequency of 225 in 40187360.

Step 1:
If we divide 4 by 225, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 225

Moving on to step 2:
225 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 225

Advancing to step 3:
The number 225 fits into 401 1 times, leaving a remainder of 176.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 225 from 401 and we're left with 176.
Grab the next digit (8) from the dividend, add it to 176, then carry on: 1768 / 225

Going ahead to step 4:
225 goes into 1768 7 times with a remainder of 193.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 193 after subtracting 1575 from 1768.
Fetch the next digit (7) from the dividend, attach it to 193 and continue: 1937 / 225

Advancing to step 5:
225 can be fit into 1937 8 times, resulting in a remainder of 137.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
The remainder is 137 after subtracting 1800 from 1937.
Append the next digit (3) from the dividend to 137 and continue with: 1373 / 225

Going ahead to step 6:
When dividing 1373 by 225, we get 6 with a remainder of 23.
The next digit of our result is 6. 
Result so far: 1786.0
If we take 1350 away from 1373, we end up with 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 225

Moving on to step 7:
If we divide 236 by 225, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 17861.0
The remainder is 11 after subtracting 225 from 236.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 225

On to step 8:
110 divided by 225 is 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 178610.0
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 9:
225 goes into 1100 4 times with a remainder of 200.
Put 4 as the next digit of the answer. 
Result so far: 178610.4
If we subtract 900 from 1100, we get 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 10:
2000 divided by 225 is 8 with a remainder of 200.
Write down 8 as next digit of the result. 
Result so far: 178610.48
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.

Let's proceed to step 11:
225 can be fit into 2000 8 times, resulting in a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 178610.488
Deduct 1800 from 2000 and we're left 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.

Our division results in 178610.488 with a remaining 0.02.
