878986 ÷ 10 
We want to figure out the number of times 878986 can be divided by 10.

Advancing to step 1:
If we divide 8 by 10, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 10

Moving on to step 2:
When dividing 87 by 10, we get 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 80 from 87 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 10

Advancing to step 3:
10 goes into 78 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 87.0
Deduct 70 from 78 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 10

On to step 4:
10 goes into 89 8 times with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 878.0
The remainder is 9 after subtracting 80 from 89.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 10

Step 5:
98 divided by 10 is 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 8789.0
Subtracting 90 from 98 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 10

On to step 6:
If we divide 86 by 10, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 87898.0
If we subtract 80 from 86, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
When dividing 60 by 10, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 87898.6
If we subtract 60 from 60, 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:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 87898.6
The remainder is 0 after subtracting 0 from 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 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 87898.6
Subtract 0 from 0 to 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.

After the division, we end up with 87898.6 and a remainder of 0.0.
