Let's divide 357807 by 9
We're looking to find how many times 9 goes into 357807.

Step 1:
3 divided by 9 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 9

On to step 2:
The number 9 fits into 35 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 27 from 35 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 9

Going ahead to step 3:
9 can be fit into 87 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 39.0
If we take 81 away from 87, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 9

Advancing to step 4:
If we divide 68 by 9, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 397.0
If we take 63 away from 68, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 9

Moving on to step 5:
If we divide 50 by 9, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3975.0
Subtracting 45 from 50 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 9

Let's proceed to step 6:
The number 9 fits into 57 6 times, leaving a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 39756.0
Subtract 54 from 57 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 9, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 39756.3
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
9 can be fit into 30 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 39756.33
Subtracting 27 from 30 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 39756.33, and the remainder is 0.003.
