We look at the division of 11685039 by 510 
Let's see how many times 510 fits into 11685039.

Let's proceed to step 1:
If we divide 1 by 510, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 510

Moving on to step 2:
510 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 510

Let's proceed to step 3:
The number 510 fits into 116 0 times, leaving a remainder of 116.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 116 to get 116.
Grab the next digit (8) from the dividend, add it to 116, then carry on: 1168 / 510

Advancing to step 4:
510 goes into 1168 2 times with a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 148 after subtracting 1020 from 1168.
Bring next digit (5) of the dividend behind the 148 and repeat the process: 1485 / 510

On to step 5:
1485 divided by 510 is 2 with a remainder of 465.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 1020 from 1485 to get 465.
Append the next digit (0) from the dividend to 465 and continue with: 4650 / 510

Moving on to step 6:
The number 510 fits into 4650 9 times, leaving a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 229.0
If we take 4590 away from 4650, we end up with 60.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 510

Step 7:
If we divide 603 by 510, we get 1 and a remainder of 93.
Put 1 as the next digit of the answer. 
Result so far: 2291.0
The remainder is 93 after subtracting 510 from 603.
Grab the next digit (9) from the dividend, add it to 93, then carry on: 939 / 510

Going ahead to step 8:
The number 510 fits into 939 1 times, leaving a remainder of 429.
Put 1 as the next digit of the answer. 
Result so far: 22911.0
Subtract 510 from 939 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 9:
510 goes into 4290 8 times with a remainder of 210.
Put 8 as the next digit of the answer. 
Result so far: 22911.8
If we take 4080 away from 4290, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
The number 510 fits into 2100 4 times, leaving a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 22911.84
The remainder is 60 after subtracting 2040 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
When dividing 600 by 510, we get 1 with a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 22911.841
Deduct 510 from 600 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
When dividing 900 by 510, we get 1 with a remainder of 390.
Use 1 as the next digit of our solution. 
Result so far: 22911.8411
Deduct 510 from 900 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The final outcome is 22911.8411, with a leftover of 0.0039.
