623416 ÷ 30 
We want to figure out the number of times 623416 can be divided by 30.

Moving on to step 1:
When dividing 6 by 30, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 30

Moving on to step 2:
62 divided by 30 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 60 away from 62, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 30

Moving on to step 3:
30 goes into 23 0 times with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 23 after subtracting 0 from 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 30

On to step 4:
234 divided by 30 is 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 207.0
If we subtract 210 from 234, we get 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 30

Advancing to step 5:
The number 30 fits into 241 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 2078.0
Subtracting 240 from 241 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 30

Advancing to step 6:
30 goes into 16 0 times with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 20780.0
If we subtract 0 from 16, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
30 goes into 160 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 20780.5
If we take 150 away from 160, 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.

Step 8:
100 divided by 30 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 20780.53
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.

Advancing to step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 20780.533
If we take 90 away from 100, 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.

In conclusion, the division gives 20780.533 with a balance of 0.001.
