We look at the division of 178802 by 90 
Let's see how many times 90 fits into 178802.

Going ahead to step 1:
If we divide 1 by 90, 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.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 90

Going ahead to step 2:
The number 90 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 90

Let's proceed to step 3:
The number 90 fits into 178 1 times, leaving a remainder of 88.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 90 from 178 and we're left with 88.
Include the next digit (8) from the dividend after 88, then repeat: 888 / 90

Moving on to step 4:
If we divide 888 by 90, we get 9 and a remainder of 78.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 810 from 888, we get 78.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 90

On to step 5:
780 divided by 90 is 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 198.0
The remainder is 60 after subtracting 720 from 780.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 90

Advancing to step 6:
90 can be fit into 602 6 times, resulting in a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 1986.0
If we subtract 540 from 602, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
When dividing 620 by 90, we get 6 with a remainder of 80.
The next digit of our result is 6. 
Result so far: 1986.6
Subtracting 540 from 620 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
When dividing 800 by 90, we get 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 1986.68
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
800 divided by 90 is 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 1986.688
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 1986.688, and the remainder is 0.008.
