30159012 ÷ 117 
Our goal is to divide 30159012 by 117.

Step 1:
117 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 117

Let's proceed to step 2:
If we divide 30 by 117, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 117

Going ahead to step 3:
The number 117 fits into 301 2 times, leaving a remainder of 67.
The next digit of our result is 2. 
Result so far: 2.0
If we take 234 away from 301, we end up with 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 117

On to step 4:
117 can be fit into 675 5 times, resulting in a remainder of 90.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 585 from 675, we get 90.
Include the next digit (9) from the dividend after 90, then repeat: 909 / 117

Step 5:
If we divide 909 by 117, we get 7 and a remainder of 90.
Write down 7 as next digit of the result. 
Result so far: 257.0
Subtract 819 from 909 to get 90.
Bring next digit (0) of the dividend behind the 90 and repeat the process: 900 / 117

Let's proceed to step 6:
117 goes into 900 7 times with a remainder of 81.
The next digit of our result is 7. 
Result so far: 2577.0
If we subtract 819 from 900, we get 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 117

Step 7:
If we divide 811 by 117, we get 6 and a remainder of 109.
Use 6 as the next digit of our solution. 
Result so far: 25776.0
Subtracting 702 from 811 leaves us with 109.
Bring next digit (2) of the dividend behind the 109 and repeat the process: 1092 / 117

Advancing to step 8:
117 can be fit into 1092 9 times, resulting in a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 257769.0
Deduct 1053 from 1092 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 9:
117 goes into 390 3 times with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 257769.3
Subtracting 351 from 390 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
117 goes into 390 3 times with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 257769.33
The remainder is 39 after subtracting 351 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 257769.33, and the remainder is 0.039.
