42248634 ÷ 30 
We want to divide 42248634 by 30.

Going ahead to step 1:
When dividing 4 by 30, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 30

Advancing to step 2:
30 can be fit into 42 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 30 away from 42, we end up with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 30

Moving on to step 3:
When dividing 122 by 30, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 120 away from 122, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 30

Step 4:
The number 30 fits into 24 0 times, leaving a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Subtract 0 from 24 to get 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 30

On to step 5:
248 divided by 30 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 1408.0
Subtracting 240 from 248 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 30

On to step 6:
If we divide 86 by 30, we get 2 and a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 14082.0
Subtract 60 from 86 to get 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 30

Step 7:
When dividing 263 by 30, we get 8 with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 140828.0
Deduct 240 from 263 and we're left with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 30

Moving on to step 8:
The number 30 fits into 234 7 times, leaving a remainder of 24.
The next digit of our result is 7. 
Result so far: 1408287.0
The remainder is 24 after subtracting 210 from 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
The number 30 fits into 240 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 1408287.8
The remainder is 0 after subtracting 240 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 30 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1408287.8
If we subtract 0 from 0, 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.

Going ahead to step 11:
30 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1408287.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1408287.8 with a remainder of 0.0.
