Let's divide 378505 by 81
We're looking to find how many times 81 goes into 378505.

Going ahead to step 1:
3 divided by 81 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 81

Advancing to step 2:
The number 81 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 81

Let's proceed to step 3:
If we divide 378 by 81, we get 4 and a remainder of 54.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 324 from 378 and we're left with 54.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 81

Let's proceed to step 4:
81 can be fit into 545 6 times, resulting in a remainder of 59.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtracting 486 from 545 leaves us with 59.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 81

Going ahead to step 5:
590 divided by 81 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 467.0
The remainder is 23 after subtracting 567 from 590.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 81

On to step 6:
The number 81 fits into 235 2 times, leaving a remainder of 73.
Write down 2 as next digit of the result. 
Result so far: 4672.0
If we subtract 162 from 235, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
81 goes into 730 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 4672.9
The remainder is 1 after subtracting 729 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
10 divided by 81 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 4672.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
81 can be fit into 100 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 4672.901
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
190 divided by 81 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 4672.9012
Subtract 162 from 190 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
280 divided by 81 is 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 4672.90123
Deduct 243 from 280 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 12:
81 goes into 370 4 times with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 4672.901234
Deduct 324 from 370 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
If we divide 460 by 81, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 4672.9012345
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 14:
81 can be fit into 550 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 4672.90123456
The remainder is 64 after subtracting 486 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 4672.90123456 with a balance of 6.4e-08.
