Let's divide 689890 by 99
Our goal is to divide 689890 by 99.

Advancing to step 1:
When dividing 6 by 99, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 99

Advancing to step 2:
99 goes into 68 0 times with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Bring next digit (9) of the dividend behind the 68 and repeat the process: 689 / 99

Moving on to step 3:
99 can be fit into 689 6 times, resulting in a remainder of 95.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 594 from 689 to get 95.
Fetch the next digit (8) from the dividend, attach it to 95 and continue: 958 / 99

Advancing to step 4:
If we divide 958 by 99, we get 9 and a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 69.0
The remainder is 67 after subtracting 891 from 958.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 99

On to step 5:
The number 99 fits into 679 6 times, leaving a remainder of 85.
Put 6 as the next digit of the answer. 
Result so far: 696.0
If we subtract 594 from 679, we get 85.
Take the next digit (0) from the dividend and append it to 85, then repeat: 850 / 99

Step 6:
99 can be fit into 850 8 times, resulting in a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 6968.0
The remainder is 58 after subtracting 792 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
99 goes into 580 5 times with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 6968.5
If we subtract 495 from 580, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 8:
If we divide 850 by 99, we get 8 and a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 6968.58
Deduct 792 from 850 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
580 divided by 99 is 5 with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 6968.585
If we take 495 away from 580, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 10:
If we divide 850 by 99, we get 8 and a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 6968.5858
Subtract 792 from 850 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
When dividing 580 by 99, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 6968.58585
Subtracting 495 from 580 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 12:
The number 99 fits into 850 8 times, leaving a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 6968.585858
The remainder is 58 after subtracting 792 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 13:
99 can be fit into 580 5 times, resulting in a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 6968.5858585
If we take 495 away from 580, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 14:
When dividing 850 by 99, we get 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 6968.58585858
If we subtract 792 from 850, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 6968.58585858 and a remainder of 5.8e-08.
