869828 ÷ 10 
We want to figure out the number of times 869828 can be divided by 10.

On to step 1:
8 divided by 10 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 10

Advancing to step 2:
86 divided by 10 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 80 from 86, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 10

Advancing to step 3:
When dividing 69 by 10, we get 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Subtract 60 from 69 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 10

On to step 4:
The number 10 fits into 98 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 869.0
If we subtract 90 from 98, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 10

Moving on to step 5:
10 can be fit into 82 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8698.0
If we subtract 80 from 82, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 10

On to step 6:
10 goes into 28 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 86982.0
Deduct 20 from 28 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
10 can be fit into 80 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 86982.8
If we subtract 80 from 80, 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.

Step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 86982.8
If we take 0 away from 0, we end up 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.

Step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 86982.8
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 86982.8, with a leftover of 0.0.
