166484 ÷ 90 
We want to divide 166484 by 90.

Going ahead to step 1:
90 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 90

Let's proceed to step 2:
90 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 90

Let's proceed to step 3:
When dividing 166 by 90, we get 1 with a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 90 from 166 and we're left with 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 90

Advancing to step 4:
90 goes into 764 8 times with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 720 away from 764, we end up with 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 90

Let's proceed to step 5:
If we divide 448 by 90, we get 4 and a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 184.0
Subtract 360 from 448 to get 88.
Include the next digit (4) from the dividend after 88, then repeat: 884 / 90

On to step 6:
90 goes into 884 9 times with a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 1849.0
The remainder is 74 after subtracting 810 from 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 7:
When dividing 740 by 90, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 1849.8
Subtracting 720 from 740 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.

Advancing to step 8:
90 goes into 200 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 1849.82
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 90 is 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 1849.822
If we take 180 away from 200, we end up 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.

After the division, we end up with 1849.822 and a remainder of 0.002.
