We're dividing 12917193 by 30 
We want to figure out the number of times 12917193 can be divided by 30.

Moving on to step 1:
1 divided by 30 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 30

Going ahead to step 2:
If we divide 12 by 30, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 30

Step 3:
If we divide 129 by 30, we get 4 and a remainder of 9.
The next digit of our result is 4. 
Result so far: 4.0
If we take 120 away from 129, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 30

Step 4:
When dividing 91 by 30, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 1 after subtracting 90 from 91.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 30

Step 5:
17 divided by 30 is 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 430.0
If we take 0 away from 17, we end up with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 30

Let's proceed to step 6:
30 can be fit into 171 5 times, resulting in a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 4305.0
Deduct 150 from 171 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 30

Let's proceed to step 7:
The number 30 fits into 219 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 43057.0
Subtract 210 from 219 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 30

Going ahead to step 8:
When dividing 93 by 30, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 430573.0
If we take 90 away from 93, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
The number 30 fits into 30 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 430573.1
If we subtract 30 from 30, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 30 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 430573.1
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 430573.1
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 430573.1 and a remainder of 0.0.
