138036 divided by 78 
Let's see how many times 78 fits into 138036.

Step 1:
If we divide 1 by 78, we get 0 and 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.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 78

Advancing to step 2:
The number 78 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 78

Advancing to step 3:
78 can be fit into 138 1 times, resulting in a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 78 from 138, we get 60.
Append the next digit (0) from the dividend to 60 and continue with: 600 / 78

Advancing to step 4:
The number 78 fits into 600 7 times, leaving a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 546 from 600 and we're left with 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 78

Let's proceed to step 5:
The number 78 fits into 543 6 times, leaving a remainder of 75.
The next digit of our result is 6. 
Result so far: 176.0
If we take 468 away from 543, we end up with 75.
Append the next digit (6) from the dividend to 75 and continue with: 756 / 78

Let's proceed to step 6:
756 divided by 78 is 9 with a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 1769.0
Subtract 702 from 756 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
If we divide 540 by 78, we get 6 and a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 1769.6
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 8:
720 divided by 78 is 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 1769.69
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
The number 78 fits into 180 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 1769.692
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
78 goes into 240 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 1769.6923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
The number 78 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1769.6923
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
When dividing 600 by 78, we get 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 1769.692307
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
When dividing 540 by 78, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 1769.6923076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 1769.69230769
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 1769.69230769, with a leftover of 1.8e-08.
