We divide 81335992 by 225
We want to divide 81335992 by 225.

Step 1:
225 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 225

Step 2:
If we divide 81 by 225, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 225

Going ahead to step 3:
225 goes into 813 3 times with a remainder of 138.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 675 from 813, we get 138.
Include the next digit (3) from the dividend after 138, then repeat: 1383 / 225

Going ahead to step 4:
When dividing 1383 by 225, we get 6 with a remainder of 33.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 1350 from 1383 to get 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 225

Let's proceed to step 5:
225 goes into 335 1 times with a remainder of 110.
Use 1 as the next digit of our solution. 
Result so far: 361.0
If we take 225 away from 335, we end up with 110.
Append the next digit (9) from the dividend to 110 and continue with: 1109 / 225

Let's proceed to step 6:
If we divide 1109 by 225, we get 4 and a remainder of 209.
Put 4 as the next digit of the answer. 
Result so far: 3614.0
If we subtract 900 from 1109, we get 209.
Grab the next digit (9) from the dividend, add it to 209, then carry on: 2099 / 225

Step 7:
The number 225 fits into 2099 9 times, leaving a remainder of 74.
The number 9 becomes the next digit in our result. 
Result so far: 36149.0
Subtract 2025 from 2099 to get 74.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 225

Moving on to step 8:
The number 225 fits into 742 3 times, leaving a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 361493.0
Deduct 675 from 742 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 9:
If we divide 670 by 225, we get 2 and a remainder of 220.
Record the quotient 2 as the next digit in the result. 
Result so far: 361493.2
Deduct 450 from 670 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
When dividing 2200 by 225, we get 9 with a remainder of 175.
Write down 9 as next digit of the result. 
Result so far: 361493.29
The remainder is 175 after subtracting 2025 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 11:
1750 divided by 225 is 7 with a remainder of 175.
Use 7 as the next digit of our solution. 
Result so far: 361493.297
If we subtract 1575 from 1750, we 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:
1750 divided by 225 is 7 with a remainder of 175.
Use 7 as the next digit of our solution. 
Result so far: 361493.2977
Deduct 1575 from 1750 and we're left 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.

The final result is 361493.2977 with a remainder of 0.00175.
