78075471 ÷ 865 
Our goal is to divide 78075471 by 865.

Advancing to step 1:
The number 865 fits into 7 0 times, leaving 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.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 865

Let's proceed to step 2:
78 divided by 865 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 865

Moving on to step 3:
865 can be fit into 780 0 times, resulting in a remainder of 780.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 780 leaves us with 780.
Append the next digit (7) from the dividend to 780 and continue with: 7807 / 865

Advancing to step 4:
7807 divided by 865 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 7785 from 7807, we get 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 865

Advancing to step 5:
225 divided by 865 is 0 with a remainder of 225.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
The remainder is 225 after subtracting 0 from 225.
Fetch the next digit (4) from the dividend, attach it to 225 and continue: 2254 / 865

On to step 6:
The number 865 fits into 2254 2 times, leaving a remainder of 524.
The next digit of our result is 2. 
Result so far: 902.0
Subtract 1730 from 2254 to get 524.
Include the next digit (7) from the dividend after 524, then repeat: 5247 / 865

Advancing to step 7:
865 goes into 5247 6 times with a remainder of 57.
Record the quotient 6 as the next digit in the result. 
Result so far: 9026.0
Subtracting 5190 from 5247 leaves us with 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 865

Going ahead to step 8:
The number 865 fits into 571 0 times, leaving a remainder of 571.
Put 0 as the next digit of the answer. 
Result so far: 90260.0
Subtracting 0 from 571 leaves us with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Let's proceed to step 9:
5710 divided by 865 is 6 with a remainder of 520.
Write down 6 as next digit of the result. 
Result so far: 90260.6
Deduct 5190 from 5710 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 10:
The number 865 fits into 5200 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 90260.66
Deduct 5190 from 5200 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 90260.66 and a remainder of 0.01.
