We divide 23959 by 78
We're looking to find how many times 78 goes into 23959.

Step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 78

Let's proceed to step 2:
78 goes into 23 0 times with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 78

Let's proceed to step 3:
78 goes into 239 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 234 from 239, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 78

Going ahead to step 4:
78 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 55, we end up with 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 78

Going ahead to step 5:
78 can be fit into 559 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 307.0
If we take 546 away from 559, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 6:
When dividing 130 by 78, we get 1 with a remainder of 52.
The next digit of our result is 1. 
Result so far: 307.1
Subtract 78 from 130 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 7:
If we divide 520 by 78, we get 6 and a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 307.16
Subtract 468 from 520 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
78 goes into 520 6 times with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 307.166
The remainder is 52 after subtracting 468 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 307.166 with a remaining 0.0052.
