We look at the division of 168887 by 90 
Our goal is to divide 168887 by 90.

Going ahead to step 1:
1 divided by 90 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 90

Moving on to step 2:
The number 90 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 90

Step 3:
If we divide 168 by 90, we get 1 and a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 90 from 168 to get 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 90

Going ahead to step 4:
When dividing 788 by 90, we get 8 with a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 720 from 788 and we're left with 68.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 90

Advancing to step 5:
If we divide 688 by 90, we get 7 and a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 187.0
Subtracting 630 from 688 leaves us with 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 90

On to step 6:
90 goes into 587 6 times with a remainder of 47.
The next digit of our result is 6. 
Result so far: 1876.0
The remainder is 47 after subtracting 540 from 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
90 can be fit into 470 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1876.5
Deduct 450 from 470 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 1876.52
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 1876.522
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 1876.522 with a remainder of 0.002.
