189479 ÷ 9 
We want to divide 189479 by 9.

Advancing to step 1:
If we divide 1 by 9, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 9

Advancing to step 2:
18 divided by 9 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 18 from 18 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 9

Advancing to step 3:
The number 9 fits into 9 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 9 from 9 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 9

On to step 4:
If we divide 4 by 9, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 210.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 9

Moving on to step 5:
47 divided by 9 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 2105.0
Deduct 45 from 47 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 9

Moving on to step 6:
The number 9 fits into 29 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 21053.0
Subtracting 27 from 29 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
20 divided by 9 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 21053.2
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 9 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 21053.22
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 21053.22 and a remainder of 0.002.
