We look at the division of 90555 by 78 
We're looking to find how many times 78 goes into 90555.

Let's proceed to step 1:
The number 78 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 78

Moving on to step 2:
If we divide 90 by 78, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 12 after subtracting 78 from 90.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 78

Let's proceed to step 3:
125 divided by 78 is 1 with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 47 after subtracting 78 from 125.
Append the next digit (5) from the dividend to 47 and continue with: 475 / 78

On to step 4:
When dividing 475 by 78, we get 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 116.0
Deduct 468 from 475 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 78

Let's proceed to step 5:
If we divide 75 by 78, we get 0 and a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 1160.0
Subtracting 0 from 75 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 6:
78 goes into 750 9 times with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 1160.9
Subtract 702 from 750 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
78 goes into 480 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 1160.96
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
The number 78 fits into 120 1 times, leaving a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 1160.961
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
When dividing 420 by 78, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 1160.9615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
300 divided by 78 is 3 with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 1160.96153
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
If we divide 660 by 78, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 1160.961538
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
78 can be fit into 360 4 times, resulting in a remainder of 48.
The next digit of our result is 4. 
Result so far: 1160.9615384
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
480 divided by 78 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 1160.96153846
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 1160.96153846 with a remainder of 1.2e-08.
