112445 ÷ 30 
We want to figure out the number of times 112445 can be divided by 30.

Step 1:
30 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 30

Step 2:
30 goes into 11 0 times with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 30

Step 3:
30 goes into 112 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 22 after subtracting 90 from 112.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 30

Let's proceed to step 4:
If we divide 224 by 30, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtracting 210 from 224 leaves us with 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 30

Moving on to step 5:
30 can be fit into 144 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 374.0
Subtract 120 from 144 to get 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 30

On to step 6:
The number 30 fits into 245 8 times, leaving a remainder of 5.
The next digit of our result is 8. 
Result so far: 3748.0
If we subtract 240 from 245, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 30 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 3748.1
If we subtract 30 from 50, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 3748.16
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
30 goes into 200 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 3748.166
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 3748.166 with a remaining 0.002.
