Let's divide 81816532 by 225
We want to figure out the number of times 81816532 can be divided by 225.

Advancing to step 1:
When dividing 8 by 225, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 225

On to step 2:
If we divide 81 by 225, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Grab the next digit (8) from the dividend, add it to 81, then carry on: 818 / 225

Moving on to step 3:
If we divide 818 by 225, we get 3 and a remainder of 143.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 675 away from 818, we end up with 143.
Grab the next digit (1) from the dividend, add it to 143, then carry on: 1431 / 225

Step 4:
If we divide 1431 by 225, we get 6 and a remainder of 81.
Use 6 as the next digit of our solution. 
Result so far: 36.0
The remainder is 81 after subtracting 1350 from 1431.
Take the next digit (6) from the dividend and append it to 81, then repeat: 816 / 225

Let's proceed to step 5:
If we divide 816 by 225, we get 3 and a remainder of 141.
Write down 3 as next digit of the result. 
Result so far: 363.0
Subtract 675 from 816 to get 141.
Grab the next digit (5) from the dividend, add it to 141, then carry on: 1415 / 225

Let's proceed to step 6:
1415 divided by 225 is 6 with a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 3636.0
If we take 1350 away from 1415, we end up with 65.
Bring next digit (3) of the dividend behind the 65 and repeat the process: 653 / 225

Advancing to step 7:
653 divided by 225 is 2 with a remainder of 203.
Use 2 as the next digit of our solution. 
Result so far: 36362.0
The remainder is 203 after subtracting 450 from 653.
Include the next digit (2) from the dividend after 203, then repeat: 2032 / 225

Going ahead to step 8:
2032 divided by 225 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 363629.0
Subtract 2025 from 2032 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
If we divide 70 by 225, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 363629.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
If we divide 700 by 225, we get 3 and a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 363629.03
The remainder is 25 after subtracting 675 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
225 goes into 250 1 times with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 363629.031
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
250 divided by 225 is 1 with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 363629.0311
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 363629.0311 with a remainder of 0.00025.
