We look at the division of 186513 by 86 
We're looking to find how many times 86 goes into 186513.

Let's proceed 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.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 86

Step 2:
If we divide 18 by 86, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 86

Step 3:
186 divided by 86 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 172 from 186, we get 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 86

Moving on to step 4:
145 divided by 86 is 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 86 from 145 leaves us with 59.
Include the next digit (1) from the dividend after 59, then repeat: 591 / 86

Going ahead to step 5:
The number 86 fits into 591 6 times, leaving a remainder of 75.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
If we take 516 away from 591, we end up with 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 86

Let's proceed to step 6:
The number 86 fits into 753 8 times, leaving a remainder of 65.
The next digit of our result is 8. 
Result so far: 2168.0
If we subtract 688 from 753, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing 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: 2168.7
Subtract 602 from 650 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 2168.75
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:
The number 86 fits into 500 5 times, leaving a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 2168.755
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 2168.755 with a remainder of 0.007.
