78959 divided by 18 
We want to figure out the number of times 78959 can be divided by 18.

On to step 1:
When dividing 7 by 18, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 18

Advancing to step 2:
18 goes into 78 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 72 from 78 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 18

Let's proceed to step 3:
69 divided by 18 is 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtracting 54 from 69 leaves us with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 18

Step 4:
155 divided by 18 is 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 438.0
Subtracting 144 from 155 leaves us with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 18

Moving on to step 5:
18 goes into 119 6 times with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 4386.0
If we take 108 away from 119, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 6:
If we divide 110 by 18, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 4386.6
Subtract 108 from 110 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
20 divided by 18 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 4386.61
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
18 goes into 20 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 4386.611
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 4386.611 with a remainder of 0.0002.
