We look at the division of 986915 by 1 
We're looking to find how many times 1 goes into 986915.

On to step 1:
When dividing 9 by 1, we get 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 9 from 9 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

On to step 2:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtract 8 from 8 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

On to step 3:
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: 986.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Going ahead to step 4:
1 goes into 9 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9869.0
The remainder is 0 after subtracting 9 from 9.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Going ahead to step 5:
1 divided by 1 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 98691.0
Deduct 1 from 1 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Moving on to step 6:
If we divide 5 by 1, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 986915.0
If we take 5 away from 5, 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.

Moving on to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 986915.0
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.
The next digit of our result is 0. 
Result so far: 986915.0
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 986915.0, with a leftover of 0.0.
