163579 ÷ 9 
We're looking to find how many times 9 goes into 163579.

On to step 1:
The number 9 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 9

Step 2:
The number 9 fits into 16 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 9 from 16 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 9

Advancing to step 3:
The number 9 fits into 73 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 72 away from 73, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 9

Step 4:
9 goes into 15 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 181.0
Subtracting 9 from 15 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 9

Going ahead to step 5:
If we divide 67 by 9, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 1817.0
Subtracting 63 from 67 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 9

Going ahead to step 6:
When dividing 49 by 9, we get 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 18175.0
If we take 45 away from 49, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
9 goes into 40 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 18175.4
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
40 divided by 9 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 18175.44
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 18175.44, with a leftover of 0.004.
