We look at the division of 86513719 by 513 
Our goal is to divide 86513719 by 513.

Moving on to step 1:
When dividing 8 by 513, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 513

Let's proceed to step 2:
513 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 513

Let's proceed to step 3:
If we divide 865 by 513, we get 1 and a remainder of 352.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 513 from 865, we get 352.
Fetch the next digit (1) from the dividend, attach it to 352 and continue: 3521 / 513

Let's proceed to step 4:
If we divide 3521 by 513, we get 6 and a remainder of 443.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 3078 from 3521 to get 443.
Take the next digit (3) from the dividend and append it to 443, then repeat: 4433 / 513

Moving on to step 5:
The number 513 fits into 4433 8 times, leaving a remainder of 329.
Write down 8 as next digit of the result. 
Result so far: 168.0
Subtract 4104 from 4433 to get 329.
Include the next digit (7) from the dividend after 329, then repeat: 3297 / 513

Moving on to step 6:
3297 divided by 513 is 6 with a remainder of 219.
Record the quotient 6 as the next digit in the result. 
Result so far: 1686.0
If we subtract 3078 from 3297, we get 219.
Take the next digit (1) from the dividend and append it to 219, then repeat: 2191 / 513

Moving on to step 7:
513 can be fit into 2191 4 times, resulting in a remainder of 139.
Put 4 as the next digit of the answer. 
Result so far: 16864.0
Subtract 2052 from 2191 to get 139.
Include the next digit (9) from the dividend after 139, then repeat: 1399 / 513

Moving on to step 8:
The number 513 fits into 1399 2 times, leaving a remainder of 373.
Use 2 as the next digit of our solution. 
Result so far: 168642.0
Deduct 1026 from 1399 and we're left with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Let's proceed to step 9:
513 can be fit into 3730 7 times, resulting in a remainder of 139.
Record the quotient 7 as the next digit in the result. 
Result so far: 168642.7
If we subtract 3591 from 3730, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 10:
513 goes into 1390 2 times with a remainder of 364.
Put 2 as the next digit of the answer. 
Result so far: 168642.72
The remainder is 364 after subtracting 1026 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 11:
If we divide 3640 by 513, we get 7 and a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 168642.727
If we subtract 3591 from 3640, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
513 can be fit into 490 0 times, resulting in a remainder of 490.
Write down 0 as next digit of the result. 
Result so far: 168642.727
If we subtract 0 from 490, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 13:
513 can be fit into 4900 9 times, resulting in a remainder of 283.
Write down 9 as next digit of the result. 
Result so far: 168642.72709
Subtract 4617 from 4900 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 14:
2830 divided by 513 is 5 with a remainder of 265.
The next digit of our result is 5. 
Result so far: 168642.727095
Subtracting 2565 from 2830 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 15:
2650 divided by 513 is 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 168642.7270955
Subtracting 2565 from 2650 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 168642.7270955 and a remainder of 8.5e-07.
