104890 divided by 90 
We want to divide 104890 by 90.

Let's proceed 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
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 90

On to step 2:
90 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 90

Let's proceed to step 3:
The number 90 fits into 104 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 90 from 104, we get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 90

Advancing to step 4:
The number 90 fits into 148 1 times, leaving a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 90 from 148, we get 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 90

On to step 5:
589 divided by 90 is 6 with a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
If we subtract 540 from 589, we get 49.
Include the next digit (0) from the dividend after 49, then repeat: 490 / 90

Moving on to step 6:
If we divide 490 by 90, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1165.0
If we take 450 away from 490, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
90 goes into 400 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 1165.4
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
When dividing 400 by 90, we get 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 1165.44
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 1165.44 with a remaining 0.04.
