3012239 ÷ 163 
Our goal is to divide 3012239 by 163.

Let's proceed to step 1:
The number 163 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 163

On to step 2:
When dividing 30 by 163, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 163

On to step 3:
When dividing 301 by 163, we get 1 with a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 163 from 301 and we're left with 138.
Include the next digit (2) from the dividend after 138, then repeat: 1382 / 163

Advancing to step 4:
163 goes into 1382 8 times with a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 1304 from 1382 to get 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 163

Let's proceed to step 5:
163 goes into 782 4 times with a remainder of 130.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
Deduct 652 from 782 and we're left with 130.
Take the next digit (3) from the dividend and append it to 130, then repeat: 1303 / 163

Step 6:
1303 divided by 163 is 7 with a remainder of 162.
Put 7 as the next digit of the answer. 
Result so far: 1847.0
If we subtract 1141 from 1303, we get 162.
Include the next digit (9) from the dividend after 162, then repeat: 1629 / 163

On to step 7:
The number 163 fits into 1629 9 times, leaving a remainder of 162.
Write down 9 as next digit of the result. 
Result so far: 18479.0
If we subtract 1467 from 1629, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 8:
163 can be fit into 1620 9 times, resulting in a remainder of 153.
Use 9 as the next digit of our solution. 
Result so far: 18479.9
Deduct 1467 from 1620 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 9:
163 goes into 1530 9 times with a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 18479.99
Subtract 1467 from 1530 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Our division results in 18479.99 with a remaining 0.063.
