We look at the division of 78123536 by 65 
We're looking to find how many times 65 goes into 78123536.

Moving on to step 1:
When dividing 7 by 65, 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.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 65

Let's proceed to step 2:
65 goes into 78 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 65 from 78, we get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 65

On to step 3:
131 divided by 65 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 1 after subtracting 130 from 131.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 65

Moving on to step 4:
If we divide 12 by 65, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 65

On to step 5:
The number 65 fits into 123 1 times, leaving a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 1201.0
The remainder is 58 after subtracting 65 from 123.
Append the next digit (5) from the dividend to 58 and continue with: 585 / 65

Step 6:
65 can be fit into 585 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 12019.0
The remainder is 0 after subtracting 585 from 585.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 65

Moving on to step 7:
The number 65 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 120190.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 65

Advancing to step 8:
36 divided by 65 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 1201900.0
Subtracting 0 from 36 leaves us 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.

Moving on to step 9:
The number 65 fits into 360 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1201900.5
If we subtract 325 from 360, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
65 goes into 350 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 1201900.55
If we take 325 away from 350, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 1201900.55 with a remaining 0.025.
