Let's divide 81040364 by 320
Let's see how many times 320 fits into 81040364.

Advancing to step 1:
320 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 320

Going ahead to step 2:
320 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 320

Advancing to step 3:
320 goes into 810 2 times with a remainder of 170.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 640 from 810 leaves us with 170.
Grab the next digit (4) from the dividend, add it to 170, then carry on: 1704 / 320

Going ahead to step 4:
The number 320 fits into 1704 5 times, leaving a remainder of 104.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 1600 from 1704 and we're left with 104.
Bring next digit (0) of the dividend behind the 104 and repeat the process: 1040 / 320

Going ahead to step 5:
1040 divided by 320 is 3 with a remainder of 80.
Write down 3 as next digit of the result. 
Result so far: 253.0
Subtracting 960 from 1040 leaves us with 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 320

Going ahead to step 6:
320 goes into 803 2 times with a remainder of 163.
Record the quotient 2 as the next digit in the result. 
Result so far: 2532.0
Subtracting 640 from 803 leaves us with 163.
Fetch the next digit (6) from the dividend, attach it to 163 and continue: 1636 / 320

Advancing to step 7:
When dividing 1636 by 320, we get 5 with a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 25325.0
Deduct 1600 from 1636 and we're left with 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 320

On to step 8:
320 goes into 364 1 times with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 253251.0
Subtracting 320 from 364 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
When dividing 440 by 320, we get 1 with a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 253251.1
Subtract 320 from 440 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
320 can be fit into 1200 3 times, resulting in a remainder of 240.
The number 3 becomes the next digit in our result. 
Result so far: 253251.13
Subtract 960 from 1200 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
320 goes into 2400 7 times with a remainder of 160.
Record the quotient 7 as the next digit in the result. 
Result so far: 253251.137
Subtract 2240 from 2400 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 12:
When dividing 1600 by 320, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 253251.1375
Deduct 1600 from 1600 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
When dividing 0 by 320, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 253251.1375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 14:
320 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 253251.1375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 253251.1375 with a remainder of 0.0.
