We're dividing 187889 by 86 
Our goal is to divide 187889 by 86.

Let's proceed to step 1:
1 divided by 86 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 86

Going ahead to step 2:
18 divided by 86 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 86

Let's proceed to step 3:
If we divide 187 by 86, we get 2 and a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 15 after subtracting 172 from 187.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 86

Going ahead to step 4:
If we divide 158 by 86, we get 1 and a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 86 from 158 to get 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 86

Moving on to step 5:
If we divide 728 by 86, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 218.0
Subtracting 688 from 728 leaves us with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 86

Moving on to step 6:
409 divided by 86 is 4 with a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 2184.0
The remainder is 65 after subtracting 344 from 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 7:
The number 86 fits into 650 7 times, leaving a remainder of 48.
The next digit of our result is 7. 
Result so far: 2184.7
If we take 602 away from 650, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
When dividing 480 by 86, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 2184.75
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
86 can be fit into 500 5 times, resulting in a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 2184.755
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 2184.755 with a remainder of 0.007.
