13972965 divided by 780 
We want to divide 13972965 by 780.

On to step 1:
1 divided by 780 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 780

On to step 2:
13 divided by 780 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 780

Moving on to step 3:
780 can be fit into 139 0 times, resulting in a remainder of 139.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 139 after subtracting 0 from 139.
Include the next digit (7) from the dividend after 139, then repeat: 1397 / 780

On to step 4:
1397 divided by 780 is 1 with a remainder of 617.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 617 after subtracting 780 from 1397.
Bring next digit (2) of the dividend behind the 617 and repeat the process: 6172 / 780

Going ahead to step 5:
If we divide 6172 by 780, we get 7 and a remainder of 712.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 5460 from 6172 to get 712.
Take the next digit (9) from the dividend and append it to 712, then repeat: 7129 / 780

Let's proceed to step 6:
780 can be fit into 7129 9 times, resulting in a remainder of 109.
Record the quotient 9 as the next digit in the result. 
Result so far: 179.0
Deduct 7020 from 7129 and we're left with 109.
Take the next digit (6) from the dividend and append it to 109, then repeat: 1096 / 780

Let's proceed to step 7:
If we divide 1096 by 780, we get 1 and a remainder of 316.
The number 1 becomes the next digit in our result. 
Result so far: 1791.0
The remainder is 316 after subtracting 780 from 1096.
Fetch the next digit (5) from the dividend, attach it to 316 and continue: 3165 / 780

Moving on to step 8:
780 goes into 3165 4 times with a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 17914.0
Subtract 3120 from 3165 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
780 can be fit into 450 0 times, resulting in a remainder of 450.
The next digit of our result is 0. 
Result so far: 17914.0
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 10:
4500 divided by 780 is 5 with a remainder of 600.
The next digit of our result is 5. 
Result so far: 17914.05
If we subtract 3900 from 4500, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 11:
780 can be fit into 6000 7 times, resulting in a remainder of 540.
The number 7 becomes the next digit in our result. 
Result so far: 17914.057
The remainder is 540 after subtracting 5460 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 12:
If we divide 5400 by 780, we get 6 and a remainder of 720.
The number 6 becomes the next digit in our result. 
Result so far: 17914.0576
Subtracting 4680 from 5400 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 13:
The number 780 fits into 7200 9 times, leaving a remainder of 180.
Write down 9 as next digit of the result. 
Result so far: 17914.05769
If we take 7020 away from 7200, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 14:
1800 divided by 780 is 2 with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 17914.057692
If we take 1560 away from 1800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 15:
The number 780 fits into 2400 3 times, leaving a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 17914.0576923
If we take 2340 away from 2400, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 16:
780 goes into 600 0 times with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 17914.0576923
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

After the division, we end up with 17914.0576923 and a remainder of 6e-07.
