689590 divided by 66 
We want to divide 689590 by 66.

Going ahead to step 1:
The number 66 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 66

On to step 2:
66 can be fit into 68 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 66 from 68 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 66

Let's proceed to step 3:
66 goes into 29 0 times with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 29 and we're left with 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 66

Going ahead to step 4:
When dividing 295 by 66, we get 4 with a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
The remainder is 31 after subtracting 264 from 295.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 66

Going ahead to step 5:
319 divided by 66 is 4 with a remainder of 55.
The number 4 becomes the next digit in our result. 
Result so far: 1044.0
If we take 264 away from 319, we end up with 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 66

Step 6:
When dividing 550 by 66, we get 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 10448.0
Deduct 528 from 550 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
66 can be fit into 220 3 times, resulting in a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 10448.3
Deduct 198 from 220 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
220 divided by 66 is 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 10448.33
The remainder is 22 after subtracting 198 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 10448.33 with a remaining 0.022.
