We're dividing 788684 by 90 
Our goal is to divide 788684 by 90.

Going ahead to step 1:
7 divided by 90 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 90

On to step 2:
When dividing 78 by 90, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 90

Going ahead to step 3:
90 can be fit into 788 8 times, resulting in a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 720 from 788 to get 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 90

Advancing to step 4:
686 divided by 90 is 7 with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtracting 630 from 686 leaves us with 56.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 90

Advancing to step 5:
90 can be fit into 568 6 times, resulting in a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 876.0
If we take 540 away from 568, we end up with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 90

On to step 6:
When dividing 284 by 90, we get 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 8763.0
The remainder is 14 after subtracting 270 from 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
The number 90 fits into 140 1 times, leaving a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 8763.1
If we take 90 away from 140, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 8763.15
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
90 goes into 500 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 8763.155
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 8763.155, with a leftover of 0.005.
