We divide 86079311 by 9
Let's see how many times 9 fits into 86079311.

Step 1:
9 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.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 9

Going ahead to step 2:
The number 9 fits into 86 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 81 away from 86, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 9

Moving on to step 3:
9 can be fit into 50 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
If we subtract 45 from 50, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 9

Let's proceed to step 4:
9 goes into 57 6 times with a remainder of 3.
The next digit of our result is 6. 
Result so far: 956.0
Subtract 54 from 57 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 9

Advancing to step 5:
If we divide 39 by 9, we get 4 and a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 9564.0
Subtract 36 from 39 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 9

Let's proceed to step 6:
33 divided by 9 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 95643.0
The remainder is 6 after subtracting 27 from 33.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 9

Advancing to step 7:
If we divide 61 by 9, we get 6 and a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 956436.0
The remainder is 7 after subtracting 54 from 61.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 9

Let's proceed to step 8:
71 divided by 9 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 9564367.0
Deduct 63 from 71 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
When dividing 80 by 9, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 9564367.8
Subtract 72 from 80 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.

On to step 10:
The number 9 fits into 80 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 9564367.88
If we subtract 72 from 80, we 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.

The quotient of the division is 9564367.88, and the remainder is 0.008.
