Let's divide 42958 by 9
We're looking to find how many times 9 goes into 42958.

Going ahead to step 1:
4 divided by 9 is 0 with a remainder of 4.
The number 0 becomes the next digit in our 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:
42 divided by 9 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 36 from 42, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 9

Advancing to step 3:
9 goes into 69 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtracting 63 from 69 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 9

Step 4:
65 divided by 9 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 477.0
The remainder is 2 after subtracting 63 from 65.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 9

Going ahead to step 5:
The number 9 fits into 28 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 4773.0
If we take 27 away from 28, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 6:
The number 9 fits into 10 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 4773.1
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 9, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 4773.11
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 4773.11 with a remaining 0.001.
