We divide 81038 by 90
Let's see how many times 90 fits into 81038.

Advancing to step 1:
The number 90 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 90

Let's proceed to step 2:
81 divided by 90 is 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 90

Let's proceed to step 3:
If we divide 810 by 90, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 810 from 810 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 90

Step 4:
3 divided by 90 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 90.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 90

Advancing to step 5:
The number 90 fits into 38 0 times, leaving a remainder of 38.
The next digit of our result is 0. 
Result so far: 900.0
If we subtract 0 from 38, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 6:
90 goes into 380 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 900.4
If we take 360 away from 380, 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.

Advancing to step 7:
If we divide 200 by 90, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 900.42
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.

Moving on to step 8:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 900.422
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 900.422 and a remainder of 0.002.
