669820 ÷ 10 
Let's see how many times 10 fits into 669820.

Step 1:
If we divide 6 by 10, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 10

Advancing to step 2:
If we divide 66 by 10, we get 6 and a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 60 from 66 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 10

Let's proceed to step 3:
When dividing 69 by 10, we get 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 66.0
The remainder is 9 after subtracting 60 from 69.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 10

On to step 4:
10 goes into 98 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 669.0
Deduct 90 from 98 and we're left with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 10

Going ahead to step 5:
If we divide 82 by 10, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 6698.0
Subtracting 80 from 82 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 10

Let's proceed to step 6:
The number 10 fits into 20 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 66982.0
Subtracting 20 from 20 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
When dividing 0 by 10, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 66982.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 10 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 66982.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 66982.0, with a leftover of 0.0.
