We divide 18369 by 78
We want to figure out the number of times 18369 can be divided by 78.

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
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 78

On to step 2:
18 divided by 78 is 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 78

Going ahead to step 3:
When dividing 183 by 78, we get 2 with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 156 from 183 leaves us with 27.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 78

On to step 4:
When dividing 276 by 78, we get 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 234 from 276 and we're left with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 78

Advancing to step 5:
429 divided by 78 is 5 with a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 235.0
The remainder is 39 after subtracting 390 from 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 6:
78 goes into 390 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 235.5
Subtracting 390 from 390 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 78 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 235.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 78 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 235.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 235.5, with a leftover of 0.0.
