We're dividing 394903 by 72 
Let's see how many times 72 fits into 394903.

Going ahead to step 1:
If we divide 3 by 72, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 72

Advancing to step 2:
39 divided by 72 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 72

Step 3:
72 can be fit into 394 5 times, resulting in a remainder of 34.
The next digit of our result is 5. 
Result so far: 5.0
If we take 360 away from 394, we end up with 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 72

Advancing to step 4:
If we divide 349 by 72, we get 4 and a remainder of 61.
The next digit of our result is 4. 
Result so far: 54.0
Subtract 288 from 349 to get 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 72

Going ahead to step 5:
72 goes into 610 8 times with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 548.0
If we take 576 away from 610, we end up with 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 72

Advancing to step 6:
If we divide 343 by 72, we get 4 and a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 5484.0
Subtracting 288 from 343 leaves us with 55.
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 7:
The number 72 fits into 550 7 times, leaving a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 5484.7
Subtract 504 from 550 to get 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 8:
When dividing 460 by 72, we get 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 5484.76
If we subtract 432 from 460, we 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.

Going ahead to step 9:
72 can be fit into 280 3 times, resulting in a remainder of 64.
The next digit of our result is 3. 
Result so far: 5484.763
Subtracting 216 from 280 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
The number 72 fits into 640 8 times, leaving a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 5484.7638
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
72 goes into 640 8 times with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 5484.76388
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 5484.76388 with a remainder of 6.4e-05.
