We look at the division of 9007505 by 90 
We want to figure out the number of times 9007505 can be divided by 90.

On to step 1:
If we divide 9 by 90, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 90

Moving on to step 2:
When dividing 90 by 90, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 90 from 90 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 90

Going ahead to step 3:
The number 90 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 0 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 90

Moving on to step 4:
90 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 100.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 90

Step 5:
90 goes into 75 0 times with a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 1000.0
Subtract 0 from 75 to get 75.
Include the next digit (0) from the dividend after 75, then repeat: 750 / 90

Step 6:
750 divided by 90 is 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 10008.0
Deduct 720 from 750 and we're left with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 90

Moving on to step 7:
If we divide 305 by 90, we get 3 and a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 100083.0
Subtract 270 from 305 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
350 divided by 90 is 3 with a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 100083.3
If we take 270 away from 350, we end up 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.

Advancing to step 9:
90 goes into 800 8 times with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 100083.38
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.

On to step 10:
When dividing 800 by 90, we get 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 100083.388
If we subtract 720 from 800, we 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.

The final outcome is 100083.388, with a leftover of 0.008.
