We look at the division of 513354 by 86 
We're looking to find how many times 86 goes into 513354.

Moving on to step 1:
When dividing 5 by 86, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 86

On to step 2:
If we divide 51 by 86, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 86

Going ahead to step 3:
When dividing 513 by 86, we get 5 with a remainder of 83.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 430 from 513 and we're left with 83.
Grab the next digit (3) from the dividend, add it to 83, then carry on: 833 / 86

Moving on to step 4:
833 divided by 86 is 9 with a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
The remainder is 59 after subtracting 774 from 833.
Include the next digit (5) from the dividend after 59, then repeat: 595 / 86

Going ahead to step 5:
The number 86 fits into 595 6 times, leaving a remainder of 79.
Use 6 as the next digit of our solution. 
Result so far: 596.0
Subtracting 516 from 595 leaves us with 79.
Include the next digit (4) from the dividend after 79, then repeat: 794 / 86

Going ahead to step 6:
86 can be fit into 794 9 times, resulting in a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 5969.0
Subtracting 774 from 794 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.

Let's proceed to step 7:
86 can be fit into 200 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 5969.2
If we take 172 away from 200, we end up with 28.
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:
86 goes into 280 3 times with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 5969.23
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
If we divide 220 by 86, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 5969.232
Deduct 172 from 220 and we're left 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.

Advancing to step 10:
When dividing 480 by 86, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5969.2325
Deduct 430 from 480 and we're left 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.

Moving on to step 11:
500 divided by 86 is 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 5969.23255
Subtracting 430 from 500 leaves us 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 5969.23255 and a remainder of 7e-05.
