We look at the division of 660767 by 90 
Let's see how many times 90 fits into 660767.

On to step 1:
6 divided by 90 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 90

Going ahead to step 2:
90 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 90

On to step 3:
If we divide 660 by 90, we get 7 and a remainder of 30.
The next digit of our result is 7. 
Result so far: 7.0
If we take 630 away from 660, we end up with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 90

Let's proceed to step 4:
307 divided by 90 is 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 37 after subtracting 270 from 307.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 90

Going ahead to step 5:
If we divide 376 by 90, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 734.0
If we take 360 away from 376, we end up with 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 90

On to step 6:
If we divide 167 by 90, we get 1 and a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 7341.0
If we subtract 90 from 167, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 7:
770 divided by 90 is 8 with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 7341.8
If we subtract 720 from 770, we get 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:
500 divided by 90 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 7341.85
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.

Let's proceed to step 9:
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: 7341.855
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.

Our division results in 7341.855 with a remaining 0.005.
