36378 ÷ 81 
Let's see how many times 81 fits into 36378.

Step 1:
3 divided by 81 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 81

Advancing to step 2:
If we divide 36 by 81, we get 0 and a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 81

Moving on to step 3:
81 can be fit into 363 4 times, resulting in a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 324 from 363 and we're left with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 81

Advancing to step 4:
If we divide 397 by 81, we get 4 and a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Deduct 324 from 397 and we're left with 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 81

Advancing to step 5:
81 can be fit into 738 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 449.0
The remainder is 9 after subtracting 729 from 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 6:
90 divided by 81 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 449.1
Deduct 81 from 90 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
81 can be fit into 90 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 449.11
The remainder is 9 after subtracting 81 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 449.11, with a leftover of 0.009.
