We're dividing 81734359 by 225 
We want to figure out the number of times 81734359 can be divided by 225.

Advancing to step 1:
When dividing 8 by 225, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 225

Step 2:
81 divided by 225 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 225

On to step 3:
If we divide 817 by 225, we get 3 and a remainder of 142.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 675 from 817 and we're left with 142.
Take the next digit (3) from the dividend and append it to 142, then repeat: 1423 / 225

On to step 4:
If we divide 1423 by 225, we get 6 and a remainder of 73.
The next digit of our result is 6. 
Result so far: 36.0
Deduct 1350 from 1423 and we're left with 73.
Bring next digit (4) of the dividend behind the 73 and repeat the process: 734 / 225

Advancing to step 5:
734 divided by 225 is 3 with a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 363.0
If we take 675 away from 734, we end up with 59.
Bring next digit (3) of the dividend behind the 59 and repeat the process: 593 / 225

On to step 6:
225 can be fit into 593 2 times, resulting in a remainder of 143.
The next digit of our result is 2. 
Result so far: 3632.0
If we take 450 away from 593, we end up with 143.
Grab the next digit (5) from the dividend, add it to 143, then carry on: 1435 / 225

Moving on to step 7:
225 goes into 1435 6 times with a remainder of 85.
Put 6 as the next digit of the answer. 
Result so far: 36326.0
Deduct 1350 from 1435 and we're left with 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 225

Moving on to step 8:
When dividing 859 by 225, we get 3 with a remainder of 184.
The number 3 becomes the next digit in our result. 
Result so far: 363263.0
Deduct 675 from 859 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 9:
225 can be fit into 1840 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 363263.8
If we take 1800 away from 1840, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
225 can be fit into 400 1 times, resulting in a remainder of 175.
Write down 1 as next digit of the result. 
Result so far: 363263.81
If we take 225 away from 400, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 11:
225 goes into 1750 7 times with a remainder of 175.
Put 7 as the next digit of the answer. 
Result so far: 363263.817
Subtract 1575 from 1750 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 12:
If we divide 1750 by 225, we get 7 and a remainder of 175.
The next digit of our result is 7. 
Result so far: 363263.8177
Subtracting 1575 from 1750 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

After the division, we end up with 363263.8177 and a remainder of 0.00175.
