We look at the division of 12153784 by 510 
We're looking to find how many times 510 goes into 12153784.

Moving on to step 1:
If we divide 1 by 510, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 510

Advancing to step 2:
If we divide 12 by 510, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 510

Step 3:
The number 510 fits into 121 0 times, leaving a remainder of 121.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 121 leaves us with 121.
Bring next digit (5) of the dividend behind the 121 and repeat the process: 1215 / 510

Moving on to step 4:
510 goes into 1215 2 times with a remainder of 195.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1020 from 1215 and we're left with 195.
Take the next digit (3) from the dividend and append it to 195, then repeat: 1953 / 510

Moving on to step 5:
If we divide 1953 by 510, we get 3 and a remainder of 423.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 1530 from 1953 and we're left with 423.
Append the next digit (7) from the dividend to 423 and continue with: 4237 / 510

Moving on to step 6:
510 can be fit into 4237 8 times, resulting in a remainder of 157.
Record the quotient 8 as the next digit in the result. 
Result so far: 238.0
If we take 4080 away from 4237, we end up with 157.
Include the next digit (8) from the dividend after 157, then repeat: 1578 / 510

Let's proceed to step 7:
When dividing 1578 by 510, we get 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 2383.0
Deduct 1530 from 1578 and we're left with 48.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 510

On to step 8:
When dividing 484 by 510, we get 0 with a remainder of 484.
Use 0 as the next digit of our solution. 
Result so far: 23830.0
Subtract 0 from 484 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 9:
If we divide 4840 by 510, we get 9 and a remainder of 250.
Put 9 as the next digit of the answer. 
Result so far: 23830.9
Deduct 4590 from 4840 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
The number 510 fits into 2500 4 times, leaving a remainder of 460.
Use 4 as the next digit of our solution. 
Result so far: 23830.94
Subtract 2040 from 2500 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 11:
4600 divided by 510 is 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 23830.949
Subtract 4590 from 4600 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
510 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 23830.949
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
1000 divided by 510 is 1 with a remainder of 490.
Write down 1 as next digit of the result. 
Result so far: 23830.94901
Deduct 510 from 1000 and we're left with 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 14:
510 goes into 4900 9 times with a remainder of 310.
Write down 9 as next digit of the result. 
Result so far: 23830.949019
Subtracting 4590 from 4900 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 15:
510 can be fit into 3100 6 times, resulting in a remainder of 40.
The next digit of our result is 6. 
Result so far: 23830.9490196
The remainder is 40 after subtracting 3060 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
The number 510 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 23830.9490196
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 23830.9490196 with a remainder of 4e-07.
