839742 ÷ 9 
We're looking to find how many times 9 goes into 839742.

Advancing to step 1:
8 divided by 9 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 9

Step 2:
83 divided by 9 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 81 from 83, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 9

Going ahead to step 3:
9 can be fit into 29 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Subtracting 27 from 29 leaves us with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 9

Let's proceed to step 4:
9 can be fit into 27 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 933.0
If we take 27 away from 27, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 9

On to step 5:
9 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 9330.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 9

Step 6:
42 divided by 9 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 93304.0
Subtract 36 from 42 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
9 goes into 60 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 93304.6
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
When dividing 60 by 9, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 93304.66
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 93304.66 with a remainder of 0.006.
