We're dividing 422845 by 9 
We want to figure out the number of times 422845 can be divided by 9.

Advancing to step 1:
4 divided by 9 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 9

Going ahead to step 2:
The number 9 fits into 42 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 36 away from 42, we end up with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 9

Let's proceed to step 3:
62 divided by 9 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
The remainder is 8 after subtracting 54 from 62.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 9

Let's proceed to step 4:
9 can be fit into 88 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 469.0
The remainder is 7 after subtracting 81 from 88.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 9

Let's proceed to step 5:
The number 9 fits into 74 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 4698.0
If we subtract 72 from 74, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 9

Step 6:
When dividing 25 by 9, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 46982.0
If we take 18 away from 25, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
70 divided by 9 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 46982.7
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
9 can be fit into 70 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 46982.77
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 46982.77 and a remainder of 0.007.
