Let's divide 425791 by 9
We want to figure out the number of times 425791 can be divided by 9.

Advancing to step 1:
9 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 9

Moving on to step 2:
42 divided by 9 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 36 from 42 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 9

Moving on to step 3:
65 divided by 9 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 47.0
If we take 63 away from 65, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 9

Step 4:
9 can be fit into 27 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 473.0
The remainder is 0 after subtracting 27 from 27.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 9

Advancing to step 5:
9 can be fit into 9 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 4731.0
If we take 9 away from 9, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 9

Step 6:
1 divided by 9 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 47310.0
Subtracting 0 from 1 leaves us 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.

Moving on to step 7:
9 goes into 10 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 47310.1
Deduct 9 from 10 and we're left 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 8:
9 goes into 10 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 47310.11
The remainder is 1 after subtracting 9 from 10.
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 47310.11 with a remaining 0.001.
