Let's divide 152139 by 78
Our goal is to divide 152139 by 78.

On to step 1:
When dividing 1 by 78, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 78

Step 2:
78 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 78

On to step 3:
When dividing 152 by 78, we get 1 with a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 78 away from 152, we end up with 74.
Include the next digit (1) from the dividend after 74, then repeat: 741 / 78

On to step 4:
78 can be fit into 741 9 times, resulting in a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 702 from 741 leaves us with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 78

Let's proceed to step 5:
393 divided by 78 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 195.0
If we subtract 390 from 393, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 78

Let's proceed to step 6:
When dividing 39 by 78, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 1950.0
If we subtract 0 from 39, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
78 goes into 390 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1950.5
Deduct 390 from 390 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.

Let's proceed to step 8:
78 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1950.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 78, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1950.5
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 1950.5 with a balance of 0.0.
