We look at the division of 91019314 by 225 
We're looking to find how many times 225 goes into 91019314.

Step 1:
If we divide 9 by 225, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 225

Going ahead to step 2:
When dividing 91 by 225, we get 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Fetch the next digit (0) from the dividend, attach it to 91 and continue: 910 / 225

Advancing to step 3:
The number 225 fits into 910 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 10 after subtracting 900 from 910.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 225

Let's proceed to step 4:
225 goes into 101 0 times with a remainder of 101.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 101 after subtracting 0 from 101.
Include the next digit (9) from the dividend after 101, then repeat: 1019 / 225

Advancing to step 5:
1019 divided by 225 is 4 with a remainder of 119.
The next digit of our result is 4. 
Result so far: 404.0
If we take 900 away from 1019, we end up with 119.
Take the next digit (3) from the dividend and append it to 119, then repeat: 1193 / 225

Going ahead to step 6:
If we divide 1193 by 225, we get 5 and a remainder of 68.
The next digit of our result is 5. 
Result so far: 4045.0
Deduct 1125 from 1193 and we're left with 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 225

Step 7:
If we divide 681 by 225, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 40453.0
The remainder is 6 after subtracting 675 from 681.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 225

Let's proceed to step 8:
If we divide 64 by 225, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 404530.0
If we subtract 0 from 64, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
The number 225 fits into 640 2 times, leaving a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 404530.2
Deduct 450 from 640 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
If we divide 1900 by 225, we get 8 and a remainder of 100.
The next digit of our result is 8. 
Result so far: 404530.28
Subtract 1800 from 1900 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
If we divide 1000 by 225, we get 4 and a remainder of 100.
Use 4 as the next digit of our solution. 
Result so far: 404530.284
Subtracting 900 from 1000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
If we divide 1000 by 225, we get 4 and a remainder of 100.
The next digit of our result is 4. 
Result so far: 404530.2844
The remainder is 100 after subtracting 900 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 404530.2844 with a remaining 0.001.
