We divide 978689 by 1
We're looking to find how many times 1 goes into 978689.

Step 1:
9 divided by 1 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 0 after subtracting 9 from 9.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Moving on to step 2:
7 divided by 1 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 97.0
If we take 7 away from 7, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Moving on to step 3:
8 divided by 1 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 978.0
Subtract 8 from 8 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Going ahead to step 4:
If we divide 6 by 1, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 9786.0
If we take 6 away from 6, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Going ahead to step 5:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 97868.0
If we take 8 away from 8, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

On to step 6:
When dividing 9 by 1, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 978689.0
The remainder is 0 after subtracting 9 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 978689.0
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.

Step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 978689.0
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.

In conclusion, the division gives 978689.0 with a balance of 0.0.
