We divide 186039 by 86
We're looking to find how many times 86 goes into 186039.

On to step 1:
86 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 86

Advancing to step 2:
18 divided by 86 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 86

Let's proceed to step 3:
If we divide 186 by 86, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 14 after subtracting 172 from 186.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 86

Advancing to step 4:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 86 away from 140, we end up with 54.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 86

Step 5:
86 goes into 543 6 times with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 216.0
The remainder is 27 after subtracting 516 from 543.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 86

On to step 6:
If we divide 279 by 86, we get 3 and a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 2163.0
Deduct 258 from 279 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
86 can be fit into 210 2 times, resulting in a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 2163.2
Deduct 172 from 210 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 2163.24
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
86 can be fit into 360 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 2163.244
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 2163.244 with a balance of 0.0016.
