We look at the division of 337015 by 86 
Let's see how many times 86 fits into 337015.

Step 1:
3 divided by 86 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 86

Going ahead to step 2:
86 goes into 33 0 times with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 86

Advancing to step 3:
If we divide 337 by 86, we get 3 and a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 79 after subtracting 258 from 337.
Take the next digit (0) from the dividend and append it to 79, then repeat: 790 / 86

Advancing to step 4:
If we divide 790 by 86, we get 9 and a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 774 from 790 to get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 86

Let's proceed to step 5:
The number 86 fits into 161 1 times, leaving a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 391.0
If we take 86 away from 161, we end up with 75.
Fetch the next digit (5) from the dividend, attach it to 75 and continue: 755 / 86

Moving on to step 6:
86 goes into 755 8 times with a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 3918.0
The remainder is 67 after subtracting 688 from 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 7:
670 divided by 86 is 7 with a remainder of 68.
Use 7 as the next digit of our solution. 
Result so far: 3918.7
Subtracting 602 from 670 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
When dividing 680 by 86, we get 7 with a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 3918.77
Subtracting 602 from 680 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 3918.77 with a balance of 0.078.
