We're dividing 978861 by 1 
We want to figure out the number of times 978861 can be divided by 1.

Let's proceed to step 1:
When dividing 9 by 1, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 9 from 9 and we're left with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

On to step 2:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Deduct 7 from 7 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Going ahead 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
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Moving on to step 4:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 9788.0
If we take 8 away from 8, we end up with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

On to step 5:
1 goes into 6 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 97886.0
Subtract 6 from 6 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Going ahead to step 6:
If we divide 1 by 1, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 978861.0
Subtracting 1 from 1 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.

Moving on 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: 978861.0
Deduct 0 from 0 and we're left 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.

Let's proceed to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 978861.0
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.

The final outcome is 978861.0, with a leftover of 0.0.
