13251 divided by 78 
Our goal is to divide 13251 by 78.

Moving on to step 1:
If we divide 1 by 78, we get 0 and 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.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 78

Let's proceed to step 2:
When dividing 13 by 78, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 78

On to step 3:
When dividing 132 by 78, we get 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 78 from 132, we get 54.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 78

Let's proceed to step 4:
The number 78 fits into 545 6 times, leaving a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 468 from 545 leaves us with 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 78

Step 5:
The number 78 fits into 771 9 times, leaving a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 169.0
If we take 702 away from 771, we end up 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.

Going ahead to step 6:
If we divide 690 by 78, we get 8 and a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 169.8
If we take 624 away from 690, we end up 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.

On to step 7:
If we divide 660 by 78, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 169.88
If we take 624 away from 660, we end up 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.

Our division results in 169.88 with a remaining 0.036.
