We look at the division of 942640 by 30 
We're looking to find how many times 30 goes into 942640.

Let's proceed to step 1:
30 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 30

Advancing to step 2:
30 goes into 94 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 90 from 94 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 30

Step 3:
30 can be fit into 42 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 30 away from 42, we end up with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 30

Going ahead to step 4:
When dividing 126 by 30, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 314.0
Subtracting 120 from 126 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 30

Moving on to step 5:
30 goes into 64 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 3142.0
Subtracting 60 from 64 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 30

Going ahead to step 6:
When dividing 40 by 30, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 31421.0
Subtract 30 from 40 to get 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 7:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 31421.3
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
30 goes into 100 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 31421.33
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 31421.33 with a remaining 0.01.
