85206879 ÷ 9 
We're looking to find how many times 9 goes into 85206879.

Step 1:
If we divide 8 by 9, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 9

On to step 2:
When dividing 85 by 9, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 81 from 85 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 9

Moving on to step 3:
9 can be fit into 42 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 94.0
Subtracting 36 from 42 leaves us with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 9

Moving on to step 4:
The number 9 fits into 60 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 946.0
Subtracting 54 from 60 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 9

Going ahead to step 5:
66 divided by 9 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 9467.0
If we take 63 away from 66, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 9

Step 6:
When dividing 38 by 9, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 94674.0
Subtracting 36 from 38 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 9

Moving on to step 7:
27 divided by 9 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 946743.0
If we take 27 away from 27, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 9

On to step 8:
9 goes into 9 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 9467431.0
Deduct 9 from 9 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.

Step 9:
0 divided by 9 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9467431.0
Subtracting 0 from 0 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.

Advancing to step 10:
The number 9 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 9467431.0
Subtracting 0 from 0 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.

The final result is 9467431.0 with a remainder of 0.0.
