We're dividing 18456 by 78 
We're looking to find how many times 78 goes into 18456.

Step 1:
When dividing 1 by 78, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 78

Let's proceed to step 2:
18 divided by 78 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 78

Let's proceed to step 3:
The number 78 fits into 184 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 156 from 184, we get 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 78

Let's proceed to step 4:
If we divide 285 by 78, we get 3 and a remainder of 51.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 51 after subtracting 234 from 285.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 78

Step 5:
The number 78 fits into 516 6 times, leaving a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 236.0
Subtract 468 from 516 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 6:
When dividing 480 by 78, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 236.6
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
78 goes into 120 1 times with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 236.61
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
78 goes into 420 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 236.615
Subtracting 390 from 420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
300 divided by 78 is 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 236.6153
Deduct 234 from 300 and we're left 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.

Let's proceed to step 10:
If we divide 660 by 78, we get 8 and a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 236.61538
Deduct 624 from 660 and we're left 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.

Advancing to step 11:
If we divide 360 by 78, we get 4 and a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 236.615384
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
480 divided by 78 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 236.6153846
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 236.61538461
The remainder is 42 after subtracting 78 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 236.61538461, and the remainder is 4.2e-08.
