71391893 ÷ 394 
Our goal is to divide 71391893 by 394.

Advancing to step 1:
If we divide 7 by 394, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 394

On to step 2:
394 goes into 71 0 times with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Fetch the next digit (3) from the dividend, attach it to 71 and continue: 713 / 394

Let's proceed to step 3:
The number 394 fits into 713 1 times, leaving a remainder of 319.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 394 from 713 and we're left with 319.
Take the next digit (9) from the dividend and append it to 319, then repeat: 3199 / 394

Step 4:
394 goes into 3199 8 times with a remainder of 47.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 3152 away from 3199, we end up with 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 394

Advancing to step 5:
When dividing 471 by 394, we get 1 with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 181.0
The remainder is 77 after subtracting 394 from 471.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 394

Advancing to step 6:
If we divide 778 by 394, we get 1 and a remainder of 384.
The next digit of our result is 1. 
Result so far: 1811.0
Deduct 394 from 778 and we're left with 384.
Bring next digit (9) of the dividend behind the 384 and repeat the process: 3849 / 394

Advancing to step 7:
If we divide 3849 by 394, we get 9 and a remainder of 303.
Put 9 as the next digit of the answer. 
Result so far: 18119.0
Subtracting 3546 from 3849 leaves us with 303.
Include the next digit (3) from the dividend after 303, then repeat: 3033 / 394

Let's proceed to step 8:
394 can be fit into 3033 7 times, resulting in a remainder of 275.
The number 7 becomes the next digit in our result. 
Result so far: 181197.0
Deduct 2758 from 3033 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 9:
2750 divided by 394 is 6 with a remainder of 386.
The next digit of our result is 6. 
Result so far: 181197.6
The remainder is 386 after subtracting 2364 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 10:
394 can be fit into 3860 9 times, resulting in a remainder of 314.
The next digit of our result is 9. 
Result so far: 181197.69
The remainder is 314 after subtracting 3546 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 11:
The number 394 fits into 3140 7 times, leaving a remainder of 382.
The number 7 becomes the next digit in our result. 
Result so far: 181197.697
If we subtract 2758 from 3140, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 12:
The number 394 fits into 3820 9 times, leaving a remainder of 274.
The number 9 becomes the next digit in our result. 
Result so far: 181197.6979
If we subtract 3546 from 3820, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 13:
394 can be fit into 2740 6 times, resulting in a remainder of 376.
Put 6 as the next digit of the answer. 
Result so far: 181197.69796
Subtract 2364 from 2740 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 14:
The number 394 fits into 3760 9 times, leaving a remainder of 214.
Write down 9 as next digit of the result. 
Result so far: 181197.697969
The remainder is 214 after subtracting 3546 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 15:
If we divide 2140 by 394, we get 5 and a remainder of 170.
Use 5 as the next digit of our solution. 
Result so far: 181197.6979695
Subtract 1970 from 2140 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 16:
The number 394 fits into 1700 4 times, leaving a remainder of 124.
The next digit of our result is 4. 
Result so far: 181197.69796954
Subtracting 1576 from 1700 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 181197.69796954 with a remainder of 1.24e-07.
