We look at the division of 86997879 by 10 
We're looking to find how many times 10 goes into 86997879.

Step 1:
10 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 10

On to step 2:
10 goes into 86 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 80 from 86 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 10

Step 3:
When dividing 69 by 10, we get 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we take 60 away from 69, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 10

Advancing to step 4:
When dividing 99 by 10, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 869.0
Subtracting 90 from 99 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 10

Advancing to step 5:
The number 10 fits into 97 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 8699.0
Subtracting 90 from 97 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 10

On to step 6:
78 divided by 10 is 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 86997.0
Subtract 70 from 78 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 10

Let's proceed to step 7:
If we divide 87 by 10, we get 8 and a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 869978.0
Subtracting 80 from 87 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 10

Advancing to step 8:
The number 10 fits into 79 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 8699787.0
The remainder is 9 after subtracting 70 from 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
When dividing 90 by 10, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 8699787.9
Subtracting 90 from 90 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.

On to step 10:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8699787.9
If we take 0 away from 0, 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.

Step 11:
0 divided by 10 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8699787.9
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 result is 8699787.9 with a remainder of 0.0.
