We look at the division of 754485 by 90 
Our goal is to divide 754485 by 90.

Step 1:
90 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 90

Let's proceed to step 2:
The number 90 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Include the next digit (4) from the dividend after 75, then repeat: 754 / 90

Going ahead to step 3:
90 can be fit into 754 8 times, resulting in a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 34 after subtracting 720 from 754.
Bring next digit (4) of the dividend behind the 34 and repeat the process: 344 / 90

Step 4:
The number 90 fits into 344 3 times, leaving a remainder of 74.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtract 270 from 344 to get 74.
Grab the next digit (8) from the dividend, add it to 74, then carry on: 748 / 90

Let's proceed to step 5:
The number 90 fits into 748 8 times, leaving a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 838.0
The remainder is 28 after subtracting 720 from 748.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 90

Moving on to step 6:
When dividing 285 by 90, we get 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 8383.0
If we take 270 away from 285, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
150 divided by 90 is 1 with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 8383.1
Deduct 90 from 150 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
90 goes into 600 6 times with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 8383.16
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
If we divide 600 by 90, we get 6 and a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 8383.166
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 8383.166 with a remainder of 0.006.
