We're dividing 11712865 by 510 
We want to figure out the number of times 11712865 can be divided by 510.

Moving on to step 1:
When dividing 1 by 510, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 510

Going ahead to step 2:
When dividing 11 by 510, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 510

On to step 3:
If we divide 117 by 510, we get 0 and a remainder of 117.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 117, we get 117.
Take the next digit (1) from the dividend and append it to 117, then repeat: 1171 / 510

Step 4:
1171 divided by 510 is 2 with a remainder of 151.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1020 from 1171, we get 151.
Append the next digit (2) from the dividend to 151 and continue with: 1512 / 510

On to step 5:
510 goes into 1512 2 times with a remainder of 492.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 492 after subtracting 1020 from 1512.
Append the next digit (8) from the dividend to 492 and continue with: 4928 / 510

Let's proceed to step 6:
If we divide 4928 by 510, we get 9 and a remainder of 338.
Record the quotient 9 as the next digit in the result. 
Result so far: 229.0
Deduct 4590 from 4928 and we're left with 338.
Append the next digit (6) from the dividend to 338 and continue with: 3386 / 510

Let's proceed to step 7:
3386 divided by 510 is 6 with a remainder of 326.
Put 6 as the next digit of the answer. 
Result so far: 2296.0
If we take 3060 away from 3386, we end up with 326.
Grab the next digit (5) from the dividend, add it to 326, then carry on: 3265 / 510

On to step 8:
510 goes into 3265 6 times with a remainder of 205.
Put 6 as the next digit of the answer. 
Result so far: 22966.0
Deduct 3060 from 3265 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 9:
510 can be fit into 2050 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 22966.4
Deduct 2040 from 2050 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
The number 510 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 22966.4
Deduct 0 from 100 and we're left 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.

Going ahead to step 11:
510 can be fit into 1000 1 times, resulting in a remainder of 490.
Use 1 as the next digit of our solution. 
Result so far: 22966.401
If we subtract 510 from 1000, 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.

Moving on to step 12:
If we divide 4900 by 510, we get 9 and a remainder of 310.
Use 9 as the next digit of our solution. 
Result so far: 22966.4019
If we subtract 4590 from 4900, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 13:
When dividing 3100 by 510, we get 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 22966.40196
Subtracting 3060 from 3100 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
510 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 22966.40196
If we take 0 away from 400, we end up 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.

On to step 15:
If we divide 4000 by 510, we get 7 and a remainder of 430.
Use 7 as the next digit of our solution. 
Result so far: 22966.4019607
If we subtract 3570 from 4000, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 16:
4300 divided by 510 is 8 with a remainder of 220.
The number 8 becomes the next digit in our result. 
Result so far: 22966.40196078
Subtract 4080 from 4300 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final result is 22966.40196078 with a remainder of 2.2e-07.
