278186 divided by 71 
We want to figure out the number of times 278186 can be divided by 71.

Advancing to step 1:
71 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 71

Moving on to step 2:
When dividing 27 by 71, we get 0 with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 71

Step 3:
If we divide 278 by 71, we get 3 and a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 213 from 278 and we're left with 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 71

Advancing to step 4:
651 divided by 71 is 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 639 away from 651, we end up with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 71

Let's proceed to step 5:
When dividing 128 by 71, we get 1 with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 391.0
Subtracting 71 from 128 leaves us with 57.
Append the next digit (6) from the dividend to 57 and continue with: 576 / 71

Step 6:
When dividing 576 by 71, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 3918.0
Subtracting 568 from 576 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
The number 71 fits into 80 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 3918.1
Subtract 71 from 80 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
71 can be fit into 90 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 3918.11
Deduct 71 from 90 and we're left 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.

After the division, we end up with 3918.11 and a remainder of 0.019.
