We're dividing 72050039 by 394 
We want to figure out the number of times 72050039 can be divided by 394.

On to step 1:
The number 394 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 394

Moving on to step 2:
394 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Take the next digit (0) from the dividend and append it to 72, then repeat: 720 / 394

Advancing to step 3:
394 can be fit into 720 1 times, resulting in a remainder of 326.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 394 from 720, we get 326.
Take the next digit (5) from the dividend and append it to 326, then repeat: 3265 / 394

Advancing to step 4:
394 can be fit into 3265 8 times, resulting in a remainder of 113.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 3152 from 3265 and we're left with 113.
Grab the next digit (0) from the dividend, add it to 113, then carry on: 1130 / 394

Moving on to step 5:
The number 394 fits into 1130 2 times, leaving a remainder of 342.
Put 2 as the next digit of the answer. 
Result so far: 182.0
Deduct 788 from 1130 and we're left with 342.
Include the next digit (0) from the dividend after 342, then repeat: 3420 / 394

Going ahead to step 6:
The number 394 fits into 3420 8 times, leaving a remainder of 268.
The next digit of our result is 8. 
Result so far: 1828.0
Subtract 3152 from 3420 to get 268.
Include the next digit (3) from the dividend after 268, then repeat: 2683 / 394

On to step 7:
When dividing 2683 by 394, we get 6 with a remainder of 319.
The next digit of our result is 6. 
Result so far: 18286.0
Subtracting 2364 from 2683 leaves us with 319.
Bring next digit (9) of the dividend behind the 319 and repeat the process: 3199 / 394

Let's proceed to step 8:
If we divide 3199 by 394, we get 8 and a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 182868.0
If we take 3152 away from 3199, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
If we divide 470 by 394, we get 1 and a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 182868.1
Subtract 394 from 470 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
760 divided by 394 is 1 with a remainder of 366.
Record the quotient 1 as the next digit in the result. 
Result so far: 182868.11
If we subtract 394 from 760, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

In conclusion, the division gives 182868.11 with a balance of 0.366.
