Let's divide 412393 by 30
Our goal is to divide 412393 by 30.

On to step 1:
The number 30 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 30

On to step 2:
30 can be fit into 41 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 30 from 41 leaves us with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 30

Advancing to step 3:
If we divide 112 by 30, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 90 from 112, we get 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 30

Step 4:
When dividing 223 by 30, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 137.0
Deduct 210 from 223 and we're left with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 30

Moving on to step 5:
30 can be fit into 139 4 times, resulting in a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 1374.0
Subtract 120 from 139 to get 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 30

Step 6:
The number 30 fits into 193 6 times, leaving a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 13746.0
Deduct 180 from 193 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 30, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 13746.4
If we take 120 away from 130, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 13746.43
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
100 divided by 30 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 13746.433
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 13746.433 with a remainder of 0.001.
