178665 divided by 90 
Our goal is to divide 178665 by 90.

Step 1:
If we divide 1 by 90, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 90

Let's proceed to step 2:
90 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 90

Advancing to step 3:
If we divide 178 by 90, we get 1 and a remainder of 88.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 90 away from 178, we end up with 88.
Append the next digit (6) from the dividend to 88 and continue with: 886 / 90

Step 4:
90 goes into 886 9 times with a remainder of 76.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 810 from 886 and we're left with 76.
Append the next digit (6) from the dividend to 76 and continue with: 766 / 90

On to step 5:
If we divide 766 by 90, we get 8 and a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 198.0
If we take 720 away from 766, we end up with 46.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 90

On to step 6:
If we divide 465 by 90, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1985.0
If we take 450 away from 465, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
If we divide 150 by 90, we get 1 and a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 1985.1
If we subtract 90 from 150, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 1985.16
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
90 can be fit into 600 6 times, resulting in a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 1985.166
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 1985.166 with a remaining 0.006.
