515418 divided by 86 
Our goal is to divide 515418 by 86.

Let's proceed to step 1:
5 divided by 86 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 86

On to step 2:
The number 86 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 86

Step 3:
If we divide 515 by 86, we get 5 and a remainder of 85.
The next digit of our result is 5. 
Result so far: 5.0
If we take 430 away from 515, we end up with 85.
Fetch the next digit (4) from the dividend, attach it to 85 and continue: 854 / 86

Step 4:
86 goes into 854 9 times with a remainder of 80.
The next digit of our result is 9. 
Result so far: 59.0
Deduct 774 from 854 and we're left with 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 86

On to step 5:
The number 86 fits into 801 9 times, leaving a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 599.0
Subtracting 774 from 801 leaves us with 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 86

Moving on to step 6:
86 goes into 278 3 times with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 5993.0
Subtracting 258 from 278 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
86 can be fit into 200 2 times, resulting in a remainder of 28.
The next digit of our result is 2. 
Result so far: 5993.2
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
The number 86 fits into 280 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 5993.23
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
If we divide 220 by 86, we get 2 and a remainder of 48.
The next digit of our result is 2. 
Result so far: 5993.232
The remainder is 48 after subtracting 172 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5993.2325
Subtract 430 from 480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
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: 5993.23255
If we take 430 away from 500, we end up 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.

After the division, we end up with 5993.23255 and a remainder of 7e-05.
