We're dividing 912505 by 90 
We want to figure out the number of times 912505 can be divided by 90.

Advancing to step 1:
90 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 90

Moving on to step 2:
The number 90 fits into 91 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 90 from 91.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 90

On to step 3:
If we divide 12 by 90, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 12, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 90

Going ahead to step 4:
125 divided by 90 is 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Subtracting 90 from 125 leaves us with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 90

Going ahead to step 5:
90 goes into 350 3 times with a remainder of 80.
Write down 3 as next digit of the result. 
Result so far: 1013.0
If we subtract 270 from 350, we get 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 90

Step 6:
The number 90 fits into 805 8 times, leaving a remainder of 85.
The next digit of our result is 8. 
Result so far: 10138.0
Subtract 720 from 805 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 7:
When dividing 850 by 90, we get 9 with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 10138.9
If we subtract 810 from 850, we 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.

Let's proceed to step 8:
If we divide 400 by 90, we get 4 and a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 10138.94
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.

Going ahead to step 9:
When dividing 400 by 90, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 10138.944
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.

The quotient of the division is 10138.944, and the remainder is 0.004.
