Let's divide 18147449 by 780
We want to figure out the number of times 18147449 can be divided by 780.

Going ahead to step 1:
780 goes into 1 0 times with 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 (8) from the dividend, add it to 1, then carry on: 18 / 780

Advancing to step 2:
The number 780 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 780

Moving on to step 3:
780 goes into 181 0 times with a remainder of 181.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 181, we get 181.
Append the next digit (4) from the dividend to 181 and continue with: 1814 / 780

On to step 4:
780 can be fit into 1814 2 times, resulting in a remainder of 254.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1560 from 1814, we get 254.
Bring next digit (7) of the dividend behind the 254 and repeat the process: 2547 / 780

On to step 5:
When dividing 2547 by 780, we get 3 with a remainder of 207.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 2340 from 2547 leaves us with 207.
Fetch the next digit (4) from the dividend, attach it to 207 and continue: 2074 / 780

Advancing to step 6:
The number 780 fits into 2074 2 times, leaving a remainder of 514.
The next digit of our result is 2. 
Result so far: 232.0
If we subtract 1560 from 2074, we get 514.
Take the next digit (4) from the dividend and append it to 514, then repeat: 5144 / 780

Step 7:
The number 780 fits into 5144 6 times, leaving a remainder of 464.
Use 6 as the next digit of our solution. 
Result so far: 2326.0
Deduct 4680 from 5144 and we're left with 464.
Fetch the next digit (9) from the dividend, attach it to 464 and continue: 4649 / 780

Advancing to step 8:
4649 divided by 780 is 5 with a remainder of 749.
Record the quotient 5 as the next digit in the result. 
Result so far: 23265.0
If we subtract 3900 from 4649, we get 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

Going ahead to step 9:
7490 divided by 780 is 9 with a remainder of 470.
The number 9 becomes the next digit in our result. 
Result so far: 23265.9
Subtracting 7020 from 7490 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 10:
The number 780 fits into 4700 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 23265.96
The remainder is 20 after subtracting 4680 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
780 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 23265.96
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
780 can be fit into 2000 2 times, resulting in a remainder of 440.
Use 2 as the next digit of our solution. 
Result so far: 23265.9602
If we take 1560 away from 2000, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 13:
780 can be fit into 4400 5 times, resulting in a remainder of 500.
Write down 5 as next digit of the result. 
Result so far: 23265.96025
If we take 3900 away from 4400, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 14:
780 goes into 5000 6 times with a remainder of 320.
The next digit of our result is 6. 
Result so far: 23265.960256
If we take 4680 away from 5000, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
3200 divided by 780 is 4 with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 23265.9602564
Subtracting 3120 from 3200 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
When dividing 800 by 780, we get 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 23265.96025641
Subtracting 780 from 800 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 23265.96025641 and a remainder of 2e-08.
