We divide 181503 by 81
We're looking to find how many times 81 goes into 181503.

Step 1:
When dividing 1 by 81, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 81

Moving on to step 2:
When dividing 18 by 81, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 81

Let's proceed to step 3:
81 goes into 181 2 times with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 162 from 181, we get 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 81

On to step 4:
The number 81 fits into 195 2 times, leaving a remainder of 33.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 162 from 195 and we're left with 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 81

Let's proceed to step 5:
The number 81 fits into 330 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 224.0
If we subtract 324 from 330, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 81

Advancing to step 6:
81 can be fit into 63 0 times, resulting in a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 2240.0
Deduct 0 from 63 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 7:
When dividing 630 by 81, we get 7 with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 2240.7
Subtracting 567 from 630 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 8:
630 divided by 81 is 7 with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 2240.77
If we subtract 567 from 630, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final outcome is 2240.77, with a leftover of 0.063.
