Let's divide 666752 by 90
We want to figure out the number of times 666752 can be divided by 90.

Going ahead to step 1:
The number 90 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 90

On to step 2:
66 divided by 90 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 90

Moving on to step 3:
If we divide 666 by 90, we get 7 and a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 630 from 666 and we're left with 36.
Include the next digit (7) from the dividend after 36, then repeat: 367 / 90

On to step 4:
90 can be fit into 367 4 times, resulting in a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 74.0
If we subtract 360 from 367, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 90

On to step 5:
90 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 740.0
If we take 0 away from 75, we end up with 75.
Bring next digit (2) of the dividend behind the 75 and repeat the process: 752 / 90

Going ahead to step 6:
90 can be fit into 752 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 7408.0
Subtracting 720 from 752 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
90 goes into 320 3 times with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 7408.3
If we take 270 away from 320, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
If we divide 500 by 90, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 7408.35
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
90 goes into 500 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 7408.355
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 7408.355 with a remaining 0.005.
