690550 ÷ 89 
Let's see how many times 89 fits into 690550.

Moving on to step 1:
If we divide 6 by 89, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 89

Step 2:
The number 89 fits into 69 0 times, leaving a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 89

Moving on to step 3:
If we divide 690 by 89, we get 7 and a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 623 from 690 and we're left with 67.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 89

Moving on to step 4:
89 can be fit into 675 7 times, resulting in a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 77.0
Deduct 623 from 675 and we're left with 52.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 89

Step 5:
89 can be fit into 525 5 times, resulting in a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 775.0
Subtracting 445 from 525 leaves us with 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 89

On to step 6:
800 divided by 89 is 8 with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 7758.0
Subtracting 712 from 800 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 7:
89 can be fit into 880 9 times, resulting in a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 7758.9
The remainder is 79 after subtracting 801 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 8:
If we divide 790 by 89, we get 8 and a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 7758.98
Subtract 712 from 790 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
When dividing 780 by 89, we get 8 with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 7758.988
If we subtract 712 from 780, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 7758.988 with a remainder of 0.0068.
