We're dividing 657690 by 90 
Our goal is to divide 657690 by 90.

On to step 1:
If we divide 6 by 90, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 90

Moving on to step 2:
If we divide 65 by 90, we get 0 and a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 90

Let's proceed to step 3:
When dividing 657 by 90, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 630 away from 657, we end up with 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 90

Step 4:
If we divide 276 by 90, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtract 270 from 276 to get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 90

Moving on to step 5:
90 goes into 69 0 times with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 730.0
Subtract 0 from 69 to get 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 90

Going ahead to step 6:
90 can be fit into 690 7 times, resulting in a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 7307.0
The remainder is 60 after subtracting 630 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
90 goes into 600 6 times with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 7307.6
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.

Moving on to step 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 7307.66
Subtract 540 from 600 to 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 7307.66 with a remainder of 0.06.
