189948 ÷ 90 
Our goal is to divide 189948 by 90.

Advancing to step 1:
The number 90 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 90

Advancing to step 2:
18 divided by 90 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 90

Going ahead to step 3:
The number 90 fits into 189 2 times, leaving a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 9 after subtracting 180 from 189.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 90

Step 4:
When dividing 99 by 90, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 90 from 99, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 90

Moving on to step 5:
90 can be fit into 94 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 211.0
If we take 90 away from 94, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 90

Let's proceed to step 6:
If we divide 48 by 90, we get 0 and a remainder of 48.
The next digit of our result is 0. 
Result so far: 2110.0
Subtract 0 from 48 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
If we divide 480 by 90, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 2110.5
The remainder is 30 after subtracting 450 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
90 goes into 300 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 2110.53
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
90 goes into 300 3 times with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 2110.533
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 2110.533 and a remainder of 0.003.
