We're dividing 90134 by 90 
Let's see how many times 90 fits into 90134.

Let's proceed to step 1:
The number 90 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 90

Going ahead to step 2:
If we divide 90 by 90, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 90 from 90 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 90

Moving on to step 3:
If we divide 1 by 90, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 90

Moving on to step 4:
The number 90 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtract 0 from 13 to get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 90

On to step 5:
If we divide 134 by 90, we get 1 and a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 1001.0
The remainder is 44 after subtracting 90 from 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 6:
440 divided by 90 is 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 1001.4
The remainder is 80 after subtracting 360 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 7:
90 goes into 800 8 times with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 1001.48
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 8:
When dividing 800 by 90, we get 8 with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 1001.488
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 1001.488, with a leftover of 0.008.
