We look at the division of 86831510 by 513 
Let's see how many times 513 fits into 86831510.

Going ahead to step 1:
513 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 513

Step 2:
The number 513 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 513

Advancing to step 3:
868 divided by 513 is 1 with a remainder of 355.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 513 away from 868, we end up with 355.
Take the next digit (3) from the dividend and append it to 355, then repeat: 3553 / 513

Going ahead to step 4:
When dividing 3553 by 513, we get 6 with a remainder of 475.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 3078 from 3553, we get 475.
Include the next digit (1) from the dividend after 475, then repeat: 4751 / 513

Moving on to step 5:
4751 divided by 513 is 9 with a remainder of 134.
Write down 9 as next digit of the result. 
Result so far: 169.0
If we take 4617 away from 4751, we end up with 134.
Fetch the next digit (5) from the dividend, attach it to 134 and continue: 1345 / 513

Let's proceed to step 6:
When dividing 1345 by 513, we get 2 with a remainder of 319.
The next digit of our result is 2. 
Result so far: 1692.0
If we subtract 1026 from 1345, we get 319.
Include the next digit (1) from the dividend after 319, then repeat: 3191 / 513

Moving on to step 7:
513 can be fit into 3191 6 times, resulting in a remainder of 113.
The number 6 becomes the next digit in our result. 
Result so far: 16926.0
Deduct 3078 from 3191 and we're left with 113.
Include the next digit (0) from the dividend after 113, then repeat: 1130 / 513

Moving on to step 8:
513 can be fit into 1130 2 times, resulting in a remainder of 104.
The next digit of our result is 2. 
Result so far: 169262.0
Subtract 1026 from 1130 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 9:
If we divide 1040 by 513, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 169262.2
Deduct 1026 from 1040 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
If we divide 140 by 513, we get 0 and a remainder of 140.
The next digit of our result is 0. 
Result so far: 169262.2
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
513 can be fit into 1400 2 times, resulting in a remainder of 374.
Record the quotient 2 as the next digit in the result. 
Result so far: 169262.202
Deduct 1026 from 1400 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 12:
513 goes into 3740 7 times with a remainder of 149.
The next digit of our result is 7. 
Result so far: 169262.2027
The remainder is 149 after subtracting 3591 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 13:
513 goes into 1490 2 times with a remainder of 464.
Record the quotient 2 as the next digit in the result. 
Result so far: 169262.20272
Subtracting 1026 from 1490 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 14:
When dividing 4640 by 513, we get 9 with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 169262.202729
Subtract 4617 from 4640 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 15:
The number 513 fits into 230 0 times, leaving a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 169262.202729
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 16:
When dividing 2300 by 513, we get 4 with a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 169262.20272904
Deduct 2052 from 2300 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The quotient of the division is 169262.20272904, and the remainder is 2.48e-07.
