We divide 13987965 by 78
Let's see how many times 78 fits into 13987965.

Advancing to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 78

Step 2:
78 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 78

Moving on to step 3:
139 divided by 78 is 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 61 after subtracting 78 from 139.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 78

Advancing to step 4:
If we divide 618 by 78, we get 7 and a remainder of 72.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 546 away from 618, we end up with 72.
Bring next digit (7) of the dividend behind the 72 and repeat the process: 727 / 78

Moving on to step 5:
727 divided by 78 is 9 with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 179.0
Subtract 702 from 727 to get 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 78

Step 6:
If we divide 259 by 78, we get 3 and a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 1793.0
The remainder is 25 after subtracting 234 from 259.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 78

Going ahead to step 7:
If we divide 256 by 78, we get 3 and a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 17933.0
Subtract 234 from 256 to get 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 78

Moving on to step 8:
78 can be fit into 225 2 times, resulting in a remainder of 69.
Use 2 as the next digit of our solution. 
Result so far: 179332.0
Deduct 156 from 225 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
78 can be fit into 690 8 times, resulting in a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 179332.8
Subtracting 624 from 690 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
The number 78 fits into 660 8 times, leaving a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 179332.88
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 179332.88 and a remainder of 0.036.
