We divide 688398 by 10
We want to divide 688398 by 10.

Let's proceed to step 1:
When dividing 6 by 10, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 10

Moving on to step 2:
The number 10 fits into 68 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 60 from 68, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 10

Step 3:
10 can be fit into 88 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
The remainder is 8 after subtracting 80 from 88.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 10

Advancing to step 4:
83 divided by 10 is 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 688.0
Deduct 80 from 83 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 10

On to step 5:
39 divided by 10 is 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 6883.0
Subtract 30 from 39 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 10

Let's proceed to step 6:
When dividing 98 by 10, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 68839.0
Subtract 90 from 98 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
When dividing 80 by 10, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 68839.8
Subtract 80 from 80 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.

Moving on to step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 68839.8
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.

Going ahead to step 9:
10 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 68839.8
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.

Our division results in 68839.8 with a remaining 0.0.
