We're dividing 28172968 by 780 
We're looking to find how many times 780 goes into 28172968.

Going ahead to step 1:
If we divide 2 by 780, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 780

Moving on to step 2:
28 divided by 780 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 780

Going ahead to step 3:
The number 780 fits into 281 0 times, leaving a remainder of 281.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 281 leaves us with 281.
Append the next digit (7) from the dividend to 281 and continue with: 2817 / 780

Let's proceed to step 4:
The number 780 fits into 2817 3 times, leaving a remainder of 477.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 2340 from 2817 leaves us with 477.
Append the next digit (2) from the dividend to 477 and continue with: 4772 / 780

Advancing to step 5:
When dividing 4772 by 780, we get 6 with a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 36.0
The remainder is 92 after subtracting 4680 from 4772.
Fetch the next digit (9) from the dividend, attach it to 92 and continue: 929 / 780

Advancing to step 6:
When dividing 929 by 780, we get 1 with a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 361.0
Deduct 780 from 929 and we're left with 149.
Fetch the next digit (6) from the dividend, attach it to 149 and continue: 1496 / 780

Advancing to step 7:
If we divide 1496 by 780, we get 1 and a remainder of 716.
The number 1 becomes the next digit in our result. 
Result so far: 3611.0
If we subtract 780 from 1496, we get 716.
Include the next digit (8) from the dividend after 716, then repeat: 7168 / 780

Advancing to step 8:
780 goes into 7168 9 times with a remainder of 148.
Write down 9 as next digit of the result. 
Result so far: 36119.0
The remainder is 148 after subtracting 7020 from 7168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 9:
780 goes into 1480 1 times with a remainder of 700.
Put 1 as the next digit of the answer. 
Result so far: 36119.1
Deduct 780 from 1480 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 10:
7000 divided by 780 is 8 with a remainder of 760.
Use 8 as the next digit of our solution. 
Result so far: 36119.18
Deduct 6240 from 7000 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 11:
780 can be fit into 7600 9 times, resulting in a remainder of 580.
Use 9 as the next digit of our solution. 
Result so far: 36119.189
If we subtract 7020 from 7600, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 12:
780 goes into 5800 7 times with a remainder of 340.
Write down 7 as next digit of the result. 
Result so far: 36119.1897
Deduct 5460 from 5800 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 13:
780 goes into 3400 4 times with a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 36119.18974
The remainder is 280 after subtracting 3120 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 14:
2800 divided by 780 is 3 with a remainder of 460.
The next digit of our result is 3. 
Result so far: 36119.189743
If we subtract 2340 from 2800, we 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.

Advancing to step 15:
4600 divided by 780 is 5 with a remainder of 700.
Use 5 as the next digit of our solution. 
Result so far: 36119.1897435
The remainder is 700 after subtracting 3900 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 16:
The number 780 fits into 7000 8 times, leaving a remainder of 760.
The number 8 becomes the next digit in our result. 
Result so far: 36119.18974358
Subtracting 6240 from 7000 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

The final outcome is 36119.18974358, with a leftover of 7.6e-07.
